Bug Description

Ubuntu 18.04.2
chromium-browser 73.0.3683.86

Network proxy is configured via Settings GUI dialog. chromium-browser is started with verbose output:

[9810:9810:0423/134338.510775:VERBOSE1:proxy_config_service_linux.cc(484)] All gsettings tests OK. Will get proxy config from gsettings.
[9810:9810:0423/134338.510926:VERBOSE1:proxy_config_service_linux.cc(1243)] Obtained proxy settings from annotation hash code 11258689
[9810:9810:0423/134338.510949:VERBOSE1:pref_proxy_config_tracker_impl.cc(184)] 0x55e7b2944b00: set chrome proxy config service to 0x55e7b27e3f10

Listing all gsettings with proxy:
~$ gsettings list-recursively | grep proxy
will return:

org.gnome.system.proxy.http host 'gse.auk.cvclab.lan'
org.gnome.system.proxy.http port 9191
org.gnome.system.proxy.http use-authentication false

org.gnome.settings-daemon.plugins.screensaver-proxy active true
org.gnome.settings-daemon.plugins.screensaver-proxy priority 0

chromium-browsers fails to connect to the internet with the error message: ERR_CONNECTION_TIMED_OUT

Starting chromium-browser with the proxy command line parameter:
~$ chromium-browser --proxy-server="gse.auk.cvclab.lan:9191"
This starts the browser and the internet connection works fine.

With Firefox there are no issues, it works with the configured system proxy settings.

Can you compare the output of the following page when chromium is launched with and without the --proxy-server command-line parameter?

    chrome://net-internals/#proxy

Doing what you say only shows two buttons: "Re-apply settings" and "Clear bad proxies". In both versions. There is nothing to compare.

What I did instead was using the net-internals events viewer.
The one which I started from command-line with a proxy shows the configured proxy.
The one which should use the system proxy shows "proxy_server":"DIRECT"

In my case, it's ignoring a file:// based pac, which looks to be intentional:

This is also not working with a http:// url based pac, which should work.

I experience the same issue on Ubuntu 20.04. Neither manual proxy settings, nor PAC file helps. Additionally, I've exported http_proxy and https_proxy environment variables wherever I could (.bashrc, .zshrc, /etc/environment)

I suppose, the fact that my PC is in the domain or that it has multiple admin users may play a role... but how?

I tried that hack with changing .desktop file
https://askubuntu.com/questions/513840/google-chrome-proxy-settings

But I found my executable in /snap/chromium/1528/bin/chromium.desktop and did not succeed to find the way to edit it (read-only file system). Moreover, this file will be rewritten during package update.

I am totally dissatisfied with the fact that I should run chromium via terminal or create some desktop shortcuts. Is there any hope that the issue will be fixed? What can I do for that?

P.S. I've tried Chromium 89.0.4389.90 - 91.0.4455.2, no one works.

UPD: I have installed Google Chrome 89.0.4389.90 (Official Build), it works properly.
