It does, see [0]. Fun fact: Signal desktop, which uses Electron under the hood, is running without sandbox on Linux [1][2].

There was a issue opened on GitHub a while back apparently but that was closed due to inactivity. What you might want to do is either open a new issue directly in GitHub (provide as much information as possible and include debug logs) or just send them a support ticket via the support form (and include debug logs).

Desktop will have it https://github.com/signalapp/Signal-Desktop/commit/9bfbee464bc307a9133ccf43042987343722afe9

Issues have been ongoing for the past couple weeks. It's not clear if this is the client or backend. Dual stack works again with v6.20.2, but IPv6-only with NAT64 still doesn't. Actively being worked on, and hopefully some good learnings. Issue link thread: https://github.com/signalapp/Signal-Desktop/issues/6439

Alive again with 6.20.2 on Windows dual stack. Directly downloaded from https://signal.org/download/

> They could at least BSL the server code and allow others to verify the server code and host but not compete.

This is exactly what they do (except they use AGPL): https://github.com/signalapp/Signal-Server

git clone https://github.com/signalapp/Signal-Server.git

yes it is available here https://github.com/signalapp/Signal-Server/blob/main/service/pom.xml

You could also start your own signal server, but with blackjack, and hookers

The fact that it locks you into using their servers, does not distribute on F-Droid (only Google Play OR an APK with an insecure update mechanism), and has a completely closed-source "abusive message filter" module server side, that could functionally be used for censorship, storing messages for future decryption, or any other number of nefarious purposes - we have no idea since it's not open source (https://github.com/signalapp/Signal-Server/blob/main/.gitmod...).

Additionally, you cannot distribute branded forks or Signal, and if you do fork it, your fork is not allowed to connect to Signal's "official" OWS (open whisper systems) servers - hostility to federation should be viewed with prejudice and suspicion at the very least, it suggests a vested interest in a single point of failure (or control), which goes against user interests.

It’s actually the signal server that isn’t reproducible because of the abusive message filter that’s in a private repository. It’s clear as day here: https://github.com/signalapp/Signal-Server
