What is a proxy error?

A proxy error happens when there's a problem with a proxy server while you're trying to access a website. These errors often come with different codes, indicating what went wrong. Common issues include problems with the proxy server, incorrect settings, or issues with the website itself.

  • Solution: Check the URL for typos.


2. HTTP 403 - Forbidden
