🤖Proxy Checker - Guide

This guide explains how to test any proxy, what each result means, and how to quickly fix common errors.


What Proxy Checker does

Proxy Checker sends a test request through your proxy and shows:

  • whether the proxy is working;

  • which public IP is returned;

  • response time;

  • error details (if something is wrong).

Use it before connecting proxy to your code, bot, browser profile, or automation tool.

Before you start

Make sure you have:

  • valid proxy credentials (if auth is required);

  • correct host and port;

  • selected protocol (HTTP/HTTPS or SOCKS5).

If your provider uses API key mode, follow your provider format for username/password.

Example (provider-specific):

http://api:YOUR_API_KEY@HOST:PORT

Step-by-step test flow

  1. Choose protocol and format, or leave Auto.

  2. Paste your proxy string (you can check up to 10 proxies at once).

  3. Click Check / Test and get results.

How to read results

Success

If test is successful, you should see:

  • status like Working, Success, or 200;

  • public IP in response;

  • response time in milliseconds.

This means proxy is ready to use.

Failed

If test fails, check the error code and message.

Common errors and quick fixes

407 Proxy Authentication Required

Meaning:

  • credentials are wrong or format is wrong.

Fix:

  • verify login/password or API key;

  • verify auth format required by your provider;

  • copy fresh credentials from your provider panel.

Timeout

Meaning:

  • connection to proxy did not complete in time.

Fix:

  • check internet/firewall;

  • verify host and port;

  • retry in 10-20 seconds;

  • test from another network if possible.

Connection refused / Could not connect

Meaning:

  • wrong host/port, blocked network, or endpoint unavailable.

Fix:

  • confirm host and port are correct;

  • verify no typo in host/port;

  • check local VPN/firewall/proxy rules.

Best practices

  • Always test with a freshly copied proxy string after changing geo/rotation/session settings.

  • Keep credentials in environment variables; do not hardcode in public code.

  • Use retries with backoff in production scripts.

  • Start with one test request before high-volume traffic.

Quick self-check checklist

Before contacting support, confirm:

  • host and port are correct;

  • protocol is correct (HTTP vs SOCKS5);

  • credentials are copied correctly;

  • Proxy Checker result and error text are saved.

If issue persists, share:

  • protocol;

  • exact error text/code;

  • sanitized proxy format (without real password/key);

  • timestamp of your last failed test.
