[🐛 Bug]: Chrome does not respect http proxy environment variables

[abbasovalex]

What happened?

I use selenium/node-chrome:109.0 when I add/pass env HTTPS_PROXY/https_proxy then Chromium does not work. Important observation: use proxy with login and password

Command used to start Selenium Grid with Docker (or Kubernetes)

docker-compose up -d --no-deps --force-recreate --build chrome109.0-1

Relevant log output

Can you try with image tag selenium/node-chrome:109.0-20250828?

[abbasovalex]

Hello! Thanks for quick answer. I tried. There is next change:

• Now if I type URI over http protocol then I see Chrome' auth popup. For exdmple, type "http://myip.com". For https URI still does not work.

Also if I into the container call printenv I see env for proxy with login and password. So I would have expected not see auth popup.

This is my docker-compose.yml with proxy credentials (real login and password were changed):
