Sometimes messages don't get send

[dataprolet]

Using a supported version?

• [X] I have searched searched open and closed issues for duplicates.
• [X] I am using Signal-Desktop as provided by the Signal team, not a 3rd-party package.

Overall summary

While using Signal-Desktop at some point the application is not sending messages anymore or rather takes extremely long (multiple minutes) for sending a message. Receiving messages works fine though. As random as the issue occurs it also solves itself.

EDIT: This is neither related so suspend/resume as in #7041 and #6103 nor to leaving the system running for a long time as in #6577.

Steps to reproduce

It's hard to reproduce because it seems to be random when the issue occurs. At one point I can send messages just fine and the next message doesn't get send.

Expected result

Well, messages should be sent immediately.

Actual result

Messages take multiple minutes to get send.

Sorry this is happening for you, but more debug info is needed to help us track this down.

The next time this happens, can you please generate a debug log (Menu -> View -> Debug Log) and find the stuck message's timestamp (hover over the message, click triple dot menu -> Info -> copy Sent timestamp) then share these 2 things? Alternatively you can also send a message with these items to Signal Support [email protected]. Thanks!

@dataprolet your logs suggest that we were unable to connect a functioning websocket to our server... is there anything unusual about your network or anything that may have changed that coincides with those messages not being sent?

[dataprolet]

No, not that I'm aware of. I'm using Pi-hole in my local network but besides that nothing unusual. Is there anything that I can do to further debug the issue?

It would be interesting to see if the problem persists with Pi-hole disabled (though I understand if you'd rather not do that).

[dataprolet]

I disabled Pi-hole for my Desktop-PC and I'm having the issue still.

I think I fixed it by lowering my MTU because of issues regarding DS-Lite.
