Galene coturn server is not configured correctly: /relay-test fails about galene_ynh

[jech]

@lapineige, no, in this case, the "unexpected EOF" means that a client disconnected without sending the close handshake. This may happen for example if a browser crashes, and is nothing to worry about.

The issue is somewhere else.

Thanks a lot for the super detailed and structured description of your issue :)

I suppose restarting both Galène and the TURN server did not work ?
Could you share your Galène ICE config file, just in case ?

Do you have any other TURN server running ? (for instance the one from Matrix-Synapse app)

Very welcome, it is me to say thx for the development of galene for ynh!

Right, restart didn't change the situation. Just found out that galene has this failure in its logs:
May 03 14:26:39 galene[876]: 2021/05/03 14:26:39 client: websocket: close 1006 (abnormal closure): unexpected EOF
Don't know it it is important...

My ./opt/yunohost/galene/data/ice-servers.json is:

[
    {
        "urls": [
            "turn:myurl.org:1194",
            "turn:myurl.org:1194?transport=tcp"
        ],
        "username": "galene",
        "credential": "XXXX"
    }
]

Two thoughts:

• Never saw the passwort XXXX (deleted the original) – is it a hash? Because it is definitely not my admin password
• I use the ynh redirect app to direct subdomains like XY.myurl.org to myurl.org/group/XY – if this is somehow interesting for the investigation into the issue.

Tell me if I can do anything further...

unexpected EOF

That means that the is an error in the End Of a File. Often an error with wrongly formatted json or such…
Maybe that ICE config file has a bad syntax ?

[jakobkilian]

Hmmm, actually it really is the content i posted... Can't see any bad syntax in that file...

Ok I tried to get myself deeper into how the turn server should work on my server. When I tried to make the turnserver listen to the default ports I got the message:

admin@XXX:/opt/yunohost/galene$ ./galene -http :8443
2021/05/10 10:23:53 Server: listen tcp :8443: bind: address already in use
admin@XXX:/opt/yunohost/galene$ ./galene -turn :1194
2021/05/10 10:24:06 Starting built-in TURN server on :1194
2021/05/10 10:24:06 Server: listen tcp :8443: bind: address already in use

Is this normal? 8443 is already inn use because of galene itself...

tcp6 0 0 :::8443 :::* LISTEN 29553/galene

Furthermore, even with coturn-galene turned off there seems to be another turnsever running. Where is this coming from (can't imagine another app using turn and din't configure it myself) and can this conflict with the coturn-galene?

When co-turn is started the server appears with netstat -tulpn as "9500/turnserver "
I also checked the Firewall and the ports (1194 and 8443) are open.

What could I check next? Or is my knowledge just to low to proceed any further? ;-)

And just to add: issue can also be reproduced by using a guest network of a Fritz.Box (Maybe the higher ports are prohibited there too?

@jakobkilian Sorry for the late reply.
You can test this other repo which uses Galène with its integrated TURN server. it doesn't work with ipv6 i believe.
sudo yunohost app install https://github.com/YunoHost-Apps/galene_ynh/tree/without-turn
Tell me if you are able to ping the TURN server with /relay-test

[jakobkilian]

Wow. It works out of the box! Thank you so much!
Also tried to set up an own server with instructions by my hoster, but naw, didn't work and I still don't really understand the whole topic -.- But for now, this works, thx!

[ericgaspar]

Someone add the same error with a different app this week. I have no idea of the problem...
