How to troubleshoot HTTP proxy connectivity issues




Many different things can cause HTTP proxies to fail to work: client configuration, server configuration, firewalls, routers, network issues, etc. Please follow these steps to troubleshoot the issue.

1. Ensure your current IP is authorized:

2. Test going to http://checkip.instantproxies.com/ manually in a browser:

3. Test different URLs to determine if the issue only occurs on a specific website.

4. Test from another computer on a different network if possible (ensure that computer's IP is authorized too).

5. Test with an alternate proxy port: ports 80, 3128, and 8800 are supported.


If the steps fail to resolve the issue, please submit a ticket noting:
1. The proxy IP and port
2. Which websites you experience issues on (and whether other websites work fine)
3. Whether the error occurs 100% of the time or only occasionally
4. A screenshot of the error you see.
Many different issues can cause a proxy to fail to work, so these details are critical for us to help identify any problems you experience.
