No internetThere is something wrong with the proxy server, or the address is incorrect.
Try:
Contacting the system admin
Checking the proxy address
Running Windows Network Diagnostics
ERR_PROXY_CONNECTION_FAILED
something wrong with the proxy server
ERR_PROXY_CONNECTION_FAILED is a browser-related error and means that proxy was not configured correctly, hence the connection failed. While in some cases, the connection problems could be related to a proxy server (meaning that it the third-party that has to fix issues), mostly the culprit is wrong configuration settings on the user's computer.
Therefore, it is usually possible to fix ERR_PROXY_CONNECTION_FAILED error relatively easily. As a first solution, you should try using an alternative browser temporarily, and see if problems persist. Also, make sure you scan your machine for malware, as it can also change your proxy settings without your permissions, resulting in ERR_PROXY_CONNECTION_FAILED error.
If that does not help, you can proceed with more advanced fixes, such as checking proxy settings, resetting TCP/IP, renewing the IP address, and more. You can find all the solutions and how to perform them here.
Good luck,
