I’ve discovered that I can only successfully connect to signal’s server with my VPN on my phone if I turn off the kill switch in the network manager.

To my knowledge this is new in the last few weeks. I’ve tried every protocol and exit servers in random countries but everything breaks with the kill switch.

This is very worrying. I sent a bug report but this feels like an intentional thing and I’m curious if others are finding that signal is trying to talk to the server via an unobscured IP address.

Extremely concerning about motives…

    I use signal on the desktop with nordvpn constantly without issue. I also use both on my phone.

      Thanks for looking, and indeed signal still works fine on my desktop computers with the VPN running.

      Really feels like their tech support was lying. I do just enough of this that the recommendation makes my eyes glaze over while sounding transparently wrong. Suddenly I need open UDP and TCP ports, but only on my phone (computer is fine) and only as of a few weeks ago (prior to that it was fine)? What?

      Allow *.whispersystems.org, *.signal.org, updates.signal.org, TCP port 443, and UDP traffic. If you have a transparent or reverse proxy it needs to support WebSockets. Signal uses a non-standard TCP port to catch filtering issues at the signaling step and also utilizes a random UDP port. All UDP ports will need to be opened. The underlying IPs are constantly changing, so it’d be hard to define accurate firewall rules.

      If the wildcard FQDN config is not working properly and you notice issues with calling, allow turn2.voip.signal.org, turn3.voip.signal.org and sfu.voip.signal.org. These are subject to change at anytime.
