Issue: How to Fix ERR_PROXY_CONNECTION_FAILED Error?

I can’t use Chrome as it continuously gives me the ERR_PROXY_CONNECTION_FAILED error, which says “There is no Internet connection. There is something wrong with the proxy server, or the address is incorrect, etc.” Please help me resolve the issue.

Solved Answer

ERR_PROXY_CONNECTION_FAILED is a browser-based error, which can occur on any Windows OS version when there are some problems with proxy settings. Proxy[1] or proxy server is a medium that connects the home network or IP with the online service / external sites. It is useful in terms of privacy protection, filtering web content or unblocking web specific web content.

Proxy does not create a direct connection to the Internet but rather establishes a connection through several servers and, therefore, disguise people’s IP addresses and other browsing-related information. Therefore, if the IP / Proxy is configured incorrectly or gets damaged during some system's configuration procedures, the ERR_PROXY_CONNECTION_FAILED error occurs. The full message says: 

There is no Internet Connection
There is something wrong with the proxy server, or the address is incorrect.
Try:
Contacting the system admin
Checking the proxy address
Running connectivity diagnostics
ERR_PROXY_CONNECTION_FAILED
