ERR_PROXY_CONNECTION_FAILED

[Marc Evans]

Good morning, everyone,

I work in a public school (college). I recently installed Debian 9 (i'm a beginner with Linux) on some PCs and we have 5 assembled Raspberry Pi to have more workstations for my students. My problem is that I can't get Chromium browsing on the college's internet network. However on the same PC I have installed Firefox too, I just changed the proxy to "manual" and I entered the college proxy/server. And bingo ! It's working fine !!

If i tried to launch Chromium i get this message : ERR_PROXY_CONNECTION_FAILED

And there is no way to get to the proxy/config menu.If I try to access Chromium "reset proxy" menu I get the following message :

chrome://linux-proxy-config/

When running Chromium under a supported desktop environment, the proxy system settings will be used. However, either your system is not supported or there was a problem launching your system configuration.
But you can still configure via the command line. Please see man chromium for more information on flags and environment variables.

As I can't access the Chromium "reset proxy" menu, I tried this tutorial (https://askubuntu.com/questions/66554/why-is-google-chrome-ignoring-my-proxy-settings) without result.

If i could get Firefox installed on my Raspberry it would not be an issue, but it's not possible.

So if any one can help me to find a way to get my network works with both browsers it would be a great relief !!

Thank you for helping me fix this problem.

ERR_PROXY_CONNECTION_FAILED is a browser-based error, it means your browser is not able to connect to the internet because of the proxy connection. Either you have invalid proxy connection or configuration of proxy is controlled by the third party. . You can usually solve this issue with the following  steps:

Change Proxy settings

Renew IP address 

Delete Proxy Server Registry Key

Reset TCP/IP
