BrowserCat API Not Loading Indian Websites: Troubleshooting Guide

If BrowserCat opens a session but an Indian website does not load, first determine whether the WebSocket connection works, whether a neutral site loads in that session, and what the target site returns. A site being hosted in India does not by itself prove that geography caused the failure. BrowserCat currently places sessions automatically near the incoming request; its region documentation says explicit region routing is on the roadmap. If you confirm that the target behaves differently by egress IP, BrowserCat documents a third-party proxy as the way to obtain precise geographic control. BrowserCat’s region documentation, checked October 3, 2026, describes the current behavior.

This guide walks through those checks with runnable Node.js and Python examples, proxy configuration, common failure patterns, and a screenshot-only alternative when you do not need a controllable browser session.

1. Diagnose the failure before changing configuration

Run the same small diagnostic against a neutral URL and the affected URL. Record whether the connection succeeds, the final URL after redirects, the HTTP status when available, navigation errors, failed requests, console messages, and whether the page has useful content. Then compare with a local browser or network if you can.

What happens	What it suggests	Next check
WebSocket connection fails before a page opens	Connection, API key, client setup, or service-side issue; this does not yet implicate the Indian website.	Check the endpoint, key, client library, and exact connection error.
Session opens, but a neutral site also fails	The problem is broader than the target site.	Inspect navigation timeout, DNS or network errors, and session behavior.
Neutral site loads; target fails in BrowserCat and locally	The target may be unavailable or rejecting the request for a reason unrelated to BrowserCat region.	Inspect response, redirects, console, and failed requests.
Neutral site loads; target fails only in BrowserCat	There is a difference between the two browsing environments.	Compare egress IP, proxy, browser state, and target response.
Target loads after egress changes through a verified India proxy	This is direct evidence that changing the egress path helped this run.	Check repeatability, proxy location, latency, reliability, and cost.

Only the last result directly demonstrates that changing the egress path helped. It does not reveal the website’s internal policy, and one successful or failed run does not establish a general rule about Indian websites.

2. Connect to BrowserCat and capture useful diagnostics

BrowserCat’s documented secure WebSocket endpoint is wss://api.browsercat.com/connect; clients send an API key header. Start with Chromium, which BrowserCat documents as the current session engine. The examples below use Playwright and save the target page’s response and browser diagnostics locally. Install Playwright with npm install playwright or pip install playwright. Create an API key in your BrowserCat account and provide it through an environment variable; do not commit it to source control or print it in logs. See the BrowserCat quick start and Playwright connection guide.

Node.js

import { chromium } from 'playwright';

const apiKey = process.env.BROWSERCAT_API_KEY;
const target = process.env.TARGET_URL ?? 'https://example.com';
if (!apiKey) throw new Error('Set BROWSERCAT_API_KEY');

const browser = await chromium.connect('wss://api.browsercat.com/connect', {
  headers: { 'Api-Key': apiKey },
});

try {
  const page = await browser.newPage();
  page.setDefaultNavigationTimeout(45_000);
  page.on('console', message => console.log('console:', message.type(), message.text()));
  page.on('requestfailed', request => console.log('request failed:', request.url(), request.failure()?.errorText));
  page.on('pageerror', error => console.log('page error:', error.message));

  try {
    const response = await page.goto(target, { waitUntil: 'domcontentloaded', timeout: 45_000 });
    console.log({
      requestedUrl: target,
      finalUrl: page.url(),
      status: response?.status() ?? null,
      title: await page.title(),
      bodyText: (await page.locator('body').innerText().catch(() => '')).slice(0, 1000),
    });
    await page.screenshot({ path: 'diagnostic.png', fullPage: true }).catch(error => {
      console.error('screenshot failed:', error.message);
    });
  } catch (error) {
    console.error('navigation failed:', error.message);
    console.log('last URL:', page.url());
  }
} finally {
  await browser.close();
}

Run it with BROWSERCAT_API_KEY and optionally TARGET_URL set in the environment. First use https://example.com as a neutral check, then set the affected URL. domcontentloaded avoids waiting indefinitely for every third-party resource; if the site renders its main content later, add a site-appropriate selector wait and record whether that wait times out.

Python

import asyncio
import os
from playwright.async_api import async_playwright

async def main():
    api_key = os.environ.get("BROWSERCAT_API_KEY")
    target = os.environ.get("TARGET_URL", "https://example.com")
    if not api_key:
        raise RuntimeError("Set BROWSERCAT_API_KEY")

    async with async_playwright() as playwright:
        browser = await playwright.chromium.connect(
            "wss://api.browsercat.com/connect",
            headers={"Api-Key": api_key},
        )
        try:
            page = await browser.new_page()
            page.set_default_navigation_timeout(45_000)
            page.on("console", lambda message: print("console:", message.type, message.text))
            page.on("requestfailed", lambda request: print(
                "request failed:", request.url, request.failure
            ))
            page.on("pageerror", lambda error: print("page error:", error))

            try:
                response = await page.goto(
                    target, wait_until="domcontentloaded", timeout=45_000
                )
                body = await page.locator("body").inner_text(timeout=5_000)
                print({
                    "requested_url": target,
                    "final_url": page.url,
                    "status": response.status if response else None,
                    "title": await page.title(),
                    "body_text": body[:1000],
                })
                await page.screenshot(path="diagnostic.png", full_page=True)
            except Exception as error:
                print("navigation failed:", repr(error))
                print("last URL:", page.url)
        finally:
            await browser.close()

asyncio.run(main())

The status can be null when navigation does not yield a main-document response. A page may return an HTTP error response and still render a useful error page, so check both status and rendered content rather than treating every response as a successful page load.

3. Check whether an India egress IP is actually needed

BrowserCat says sessions are placed automatically near the incoming request, and its documentation does not provide a current way to pin a session to India. Session placement near the caller does not establish that the target sees an Indian IP. That is an inference from BrowserCat’s placement and proxy guidance, so verify the actual egress address from the running browser session before choosing a location-based fix. BrowserCat’s region guide says precise geographic control currently requires a third-party proxy.

To inspect egress, navigate to an IP-echo service that you trust and inspect the address and its reported location from the browser session. Treat geolocation databases as estimates: they can disagree, and an IP’s registered location is not conclusive proof of the route a particular target observes. Repeat the check with the affected URL and with the proposed proxy enabled. Do not share API keys, proxy usernames, or passwords in public tickets or comments.

4. Configure a third-party proxy when the evidence supports it

BrowserCat does not include a built-in proxy service. Its proxy configuration is passed inside the JSON BrowserCat-Opts header:

Option	Required?	Meaning
server	Yes	The proxy server URL supplied by your proxy provider, including scheme and port as required.
username	No	Proxy authentication username, if the provider requires it.
password	No	Proxy authentication password, if required.
bypass	No	Comma-separated domain patterns that should bypass the proxy. A bypass match can make a request use a different egress path than expected.

Use a provider that explicitly offers the India country or city you need, and verify the session’s observed egress address. BrowserCat names cost, speed, and reliability as proxy trade-offs; also compare location coverage, success with your target, authentication method, and whether the offered addresses fit your use case. BrowserCat does not endorse a particular proxy provider. Read its third-party proxy instructions.

Node.js with proxy options

import { chromium } from 'playwright';

const apiKey = process.env.BROWSERCAT_API_KEY;
const proxyServer = process.env.PROXY_SERVER;
const target = process.env.TARGET_URL;
if (!apiKey || !proxyServer || !target) {
  throw new Error('Set BROWSERCAT_API_KEY, PROXY_SERVER, and TARGET_URL');
}

const proxy = { server: proxyServer };
if (process.env.PROXY_USERNAME) proxy.username = process.env.PROXY_USERNAME;
if (process.env.PROXY_PASSWORD) proxy.password = process.env.PROXY_PASSWORD;
if (process.env.PROXY_BYPASS) proxy.bypass = process.env.PROXY_BYPASS;

const browser = await chromium.connect('wss://api.browsercat.com/connect', {
  headers: {
    'Api-Key': apiKey,
    'BrowserCat-Opts': JSON.stringify({ proxy }),
  },
});
try {
  const page = await browser.newPage();
  const response = await page.goto(target, {
    waitUntil: 'domcontentloaded',
    timeout: 45_000,
  });
  console.log({ finalUrl: page.url(), status: response?.status() ?? null });
} finally {
  await browser.close();
}

Python with proxy options

import asyncio
import json
import os
from playwright.async_api import async_playwright

async def main():
    api_key = os.environ.get("BROWSERCAT_API_KEY")
    proxy_server = os.environ.get("PROXY_SERVER")
    target = os.environ.get("TARGET_URL")
    if not api_key or not proxy_server or not target:
        raise RuntimeError("Set BROWSERCAT_API_KEY, PROXY_SERVER, and TARGET_URL")

    proxy = {"server": proxy_server}
    if os.getenv("PROXY_USERNAME"):
        proxy["username"] = os.environ["PROXY_USERNAME"]
    if os.getenv("PROXY_PASSWORD"):
        proxy["password"] = os.environ["PROXY_PASSWORD"]
    if os.getenv("PROXY_BYPASS"):
        proxy["bypass"] = os.environ["PROXY_BYPASS"]

    async with async_playwright() as playwright:
        browser = await playwright.chromium.connect(
            "wss://api.browsercat.com/connect",
            headers={
                "Api-Key": api_key,
                "BrowserCat-Opts": json.dumps({"proxy": proxy}),
            },
        )
        try:
            page = await browser.new_page()
            response = await page.goto(
                target, wait_until="domcontentloaded", timeout=45_000
            )
            print({"final_url": page.url, "status": response.status if response else None})
        finally:
            await browser.close()

asyncio.run(main())

Supply the proxy endpoint and credentials through environment variables or a secret manager. Avoid logging the serialized options header because it contains credentials. Test without bypass first; add bypass rules only when you intend those domains to connect outside the proxy.

5. Understand option precedence and browser compatibility

BrowserCat accepts browser configuration through the BrowserCat-Opts header and supports a subset through query parameters. If a key appears in both, the header value takes precedence. Remove stale or duplicate values while diagnosing, especially a proxy setting or region value that differs between locations. BrowserCat also documents query-parameter alternatives for clients that cannot set headers, including JSON-encoded configuration and an apiKey query parameter; use only wss or https because URL-carried credentials can otherwise be exposed in transit. Prefer headers when the client supports them. See BrowserCat configuration overview.

As checked for this guide, BrowserCat documents Chromium and Chrome sessions as available, while Firefox and WebKit are roadmap items. Use the documented Chromium connection first to rule out an unsupported browser-engine choice. BrowserCat’s browser type documentation describes those options. Region configuration should not be mistaken for a current India pin: the region page says explicit region selection is on the roadmap.

6. Troubleshooting common errors

Symptom	Likely cause to investigate	Fix or next diagnostic
WebSocket handshake rejected	Wrong endpoint, missing or invalid API key, or malformed connection options.	Use wss://api.browsercat.com/connect, check the key header spelling and value, and remove optional configuration until a minimal connection works.
Navigation timeout	The main document or a chosen readiness condition did not complete in time; slow resources or a hanging page can contribute.	Record the last URL and failed requests. Start with domcontentloaded, set a finite timeout, and wait for a site-specific selector only when required.
Target returns 403, 429, or an interstitial	The target returned a denial, rate limit, or challenge response to this request.	Record status, final URL, visible page text, and response behavior. Compare local and remote runs. Do not assume an India block or attempt to evade a site’s access controls.
Neutral site succeeds, target fails	Target-specific behavior, URL/redirect issue, browser state, or network dependencies.	Inspect redirects, console output, failed subresource requests, and whether the target requires cookies or a prior navigation.
Proxy authentication or connection error	Credentials, URL scheme, port, or provider configuration may be wrong.	Confirm the exact endpoint and authentication method with the proxy provider; validate the proxy independently and keep credentials secret.
Proxy enabled but target sees a different location	A bypass rule may exclude the target; the selected endpoint may not be in India; IP geolocation may be inaccurate.	Remove bypass temporarily, inspect egress again from the browser, and verify the provider’s location coverage.
Header option appears ignored	A query parameter/header conflict, malformed JSON, or client that omits custom headers.	Log only redacted option names, validate JSON locally, remove duplicate keys, and confirm the library forwards headers on the WebSocket handshake.
Local machine works, BrowserCat does not	Different egress, browser state, or network path.	Compare observed egress and response details. Add a verified proxy only if the evidence points to location or IP differences.

7. Performance, reliability, and cost considerations

• Keep the diagnostic small. Test one neutral URL and one target, and use a finite navigation timeout. A full-page screenshot and verbose request logging add work; turn them on only when they help answer the question.
• Proxy latency is part of page load. A geographically distant or overloaded proxy can increase connection and navigation time. Compare runs with the same URL and wait condition, and distinguish a slow response from a failed one.
• Repeat before making a durable change. A single timeout can be transient. Re-run a small number of controlled comparisons and preserve timestamps, status, redirects, and egress observations.
• Choose proxy trade-offs deliberately. Compare price, speed, reliability, location coverage, and the provider’s IP type for the task. No proxy provider is endorsed here.
• Track the cost of your actual setup. BrowserCat’s proxy service is third-party and separately selected; confirm its pricing and terms directly with the provider. The research reviewed for this guide found no verified BrowserCat statistic or proxy-vendor recommendation to cite.

8. Or skip the browser setup

If you only need a clean screenshot or PDF and do not need to drive an interactive browser session, ScreenshotNeo is a website screenshot API and MCP server. Its one-call API captures a URL as PNG, JPEG, WebP, or PDF. See the ScreenshotNeo API documentation.

curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webp

import requests
r = requests.get("https://api.screenshotneo.com/v1/shot", params={"access_key": "YOUR_API_KEY", "url": "https://stripe.com"}, timeout=90)
open("shot.webp", "wb").write(r.content)

const q = new URLSearchParams({ access_key: 'YOUR_API_KEY', url: 'https://stripe.com' });
const res = await fetch(`https://api.screenshotneo.com/v1/shot?${q}`);
if (!res.ok) throw new Error(`Screenshot request failed: ${res.status}`);
await Bun.write('shot.webp', res);

ScreenshotNeo removes cookie and consent banners, newsletter popups, and chat widgets before capture; each cleanup step can be turned off. Bot checks, blank pages, failed loads, timeouts, and cache hits are not billed, and response headers say which page verdict was returned and whether the capture was billed. Its MCP server gives AI agents tools to take screenshots, get page information, and capture PDFs. The free plan includes 1,000 screenshots per month without a card; paid plans start at $5 for 3,000 screenshots. Sign up for 1,000 free screenshots a month, with no card required.

9. Frequently asked questions

Can I pin a BrowserCat session to India?

BrowserCat’s region documentation checked October 3, 2026 says explicit region selection is on the roadmap. It currently describes automatic placement near the incoming request. For precise location control today, it points to a third-party proxy.

Does an Indian website failing prove it blocks BrowserCat?

No. Compare a neutral site, inspect the target’s response and redirects, and compare the same target from another network. A failure alone does not identify its cause.

Should I use BrowserCat’s region setting or a proxy?

Do not treat the region setting as an India guarantee. If your test indicates that egress location matters, use a proxy that offers the needed India location and verify the observed egress IP.

Which browser should I test first?

Use Chromium, which BrowserCat documents as currently supported. Its browser-type documentation lists Firefox and WebKit as coming soon.

When is ScreenshotNeo a suitable alternative?

Use it when the task is to obtain a screenshot or PDF from a URL. Keep BrowserCat when your task needs an interactive browser session and automation.
