Failed to start Sygnal/Matrix Pusher

[tom-zemingo]

It seems like the Sygnal process is constantly 'activating'. Tried to change the port number via the sygnal.yaml file, tried to stop & start the sygnal process (and the server) and tried to kill the process. All attempts were no useful and the service is still not running.

I get the following: Jun 20 15:04:24 ip-10-0-1-29 bash[3425]: 2021-06-20 15:04:24,025 [3425] INFO [_legacy.py:154] twisted SygnalLoggedSite starting on 8008 Jun 20 15:04:24 ip-10-0-1-29 bash[3425]: 2021-06-20 15:04:24,026 [3425] INFO [_legacy.py:154] twisted Starting factory <sygnal.http.SygnalLoggedSite object at 0x7f240e8c3ad0> Jun 20 15:05:53 ip-10-0-1-29 systemd[1]: sygnal.service: Start operation timed out.

What am I missing?

This looks like it is trying to bind in an in-use port.

There's a #sygnal:matrix.org channel which can be used for discussion, please redirect support queries there!

[tom-zemingo]

@clokep where can I find #sygnal:matrix.org channel? Can you send a link?

[clokep]

Can you send a link?

https://matrix.to/#/#sygnal:matrix.org

It should be joinable from any Matrix channel.
