In my system

# lsb_release -a

I have compiled with go:

Starting the server:

When I try to connect from Talk:

The exact same test with nextcloud-spreed-signaling v0.4.1 in the same system works fine.

Most likely a duplicate of #180, did you check the comments there?

[pmarini-nc]

Yes, confirmed. Maybe a note in the Readme about this would help?

Thanks.
