Signal does not get proxy settings from Gnome

[KonstantinHirsch]

Version: 7.3.1, flatpak
Flatpak version: 1.15.6
Operating System: OpenSuse Tumbleweed
Desktop Environment: Gnome 46

Signal cannot connect as it seems not be able to retrieve the correct proxy settings, which are set up using NetworkManager. It seems that this is supposed to be handled by the proxy resolver portal as described here: https://discussion.fedoraproject.org/t/flatpak-apps-not-automatically-using-system-proxy-set-from-gnome-settings/107860/7

Thanks in advance.

From your linked thread (https://discussion.fedoraproject.org/t/107860/8)

This will be handled transparently if you use GProxyResolver, which basically all GNOME applications will do. Third-party applications might need code changes for that to work, though.

Signal is not a GNOME application, so it will not use the portal. This should be done on the Electron side of things.
How do others do this?

I am no developer, so I do not know. But as I understand it, this here is the flatpak version of signal, and therefore the network proxy information should be retrieved by the appropriate portal, in this case the proxy resolver protal. But again, I am no developer, but have the issue that the proxy settings are not retrieved correctly for the signal flatpak app.

Is there anything I can help with to resolve this issue?

I had this same problem, using Mate (Ubuntu Mate).

I couldn't get it working even if I added proxy environment variables with flatseal (with the correct variables it didn't show network error, but still didn't work).

Ultimately, I had to switch to the deb version of Signal, but I hope this can be fixed.
