Coturn server installed for spreed.me keeps returning in log cannot create tls listener

[equynox]

Hi there,

First i would like you to know that i am a newbie in linux but i think i did a pretty good job setting up my own centos 7 VPS box with vestaCP nextcloud, spreed,me and coturn just following tutorials and when it was not working using my common sense to solve the problem.

Though the coturn server is up and running and tested from different networks to check if i can connect video and audio over spreed.me and worked flawlessly i still have this error message in log file

and the log continues like this up until server id=64.

Anyone has any ideea?

Is the coturn server running as root? If not you are not able to bind a port lower then 1000. Can you post your turnserver.conf?

[equynox]

port are higher than 1000, and its not running as root i added a user coturn in apache group but anyway here is my turnserver.conf

#Run as TURN server only, all STUN requests will be ignored.
no-stun

#Specify listening port. Change to 80 or 443 to go around some strict NATs.
listening-port=3478

but i created in /etc/systemd/system a coturn.service as i said not running on root
[Unit]

Group=apache
ExecStart=/usr/local/bin/turnserver -c /etc/turnserver.conf -l /var/log/coturn.log

[Install]
WantedBy=multi-user.target

should i replace user with root and group with root or just delete group and leave just user root?

[equynox]

Tried with root in Init script user=root group=root and the output error stays the same…

@equynox

/home/admin/conf/web/ssl.cloud.ghid-pitesti.ro.pem

Is the user who is running coturn able to read that?

Here for reference my working trunserver.conf

[equynox]

Ok so i know that the server is running checked here https://webrtc_github_io/samples/src/content/peerconnection/trickle-ice/ resolving the IPs behind NAT_

I verified video connectivity with spreed server_me sever through nextcloud_ Everything worked fine_

Mobile - Android 7 Chrome -> Mobile Android 6 Chrome - (Same bearer) => Worked both ways video+audio
Mobile - Android 7 Chrome -> Mobile Android 6 Chrome - (WiFi Home) => Worked both ways video+audio
Mobile - Android 7 Chrome (GSM) -> Laptop Chrome (WiFi Home) => Worked both ways video+audio
Mobile - Android 7 Chrome (GSM) -> Android 5 Chrome (GSM Different bearer) = Worked just one way with video and audio both ways) and the same with a 4_4 KitKat_ (dont know if it is compatiblity issue)

Anyway so, spreed and coturn are almost functional with minor glitches

But,

I keep getting the this output

So, i have TLS/TCP listeners opened on every turnserver (64) opened, but still why do i get the messages Cannot create TLS Listener, socket: Protocol not supported and after the listeners are opened_ Is it ok?

And why do i have like 64 ids of turnserver?

[equynox]

Ok, i changed Init script for turnserver to user root group root and message “cannot create tls listener” dissappearred. Probably read permissions for the coturn user that I created.

Still the other one remains together with the message socket:protocol not supported. And why 64 id’s for the turnserver instance.
