[Solved] Installation coturn TURN-Server

ℹ️ Support 💬 Talk (spreed)

Hello everyone,
I have a Nextcloud installation at a shared hoster (All-Inkl) and also use the videocall-App. Unfortunately the app only works when both paticipants in a conversation use (also different) LAN/WLAN-nets. It does not work from a LAN-net to a mobile phone.
I suppose this does not work because of the missing TURN-server.
I would like to install coturn on another server (V-server).
Does something like that work and if, how?
I would really appreciate if someone could explain the single steps to me.
Ubuntu 16.04 is running on the V-server and I can reach the server via its IP-address.

Thanks very much in advance

You can use this explanation here to install coturn on your server:

/etc/turnserver.conf should then contain something like:
listening-port=3478
fingerprint
lt-cred-mech
use-auth-secret
static-auth-secret=the-shared-secret-from-above
realm=Spreedbox
total-quota=100
bps-capacity=0
stale-nonce
cipher-list="ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+3DES:DH+3DES:RSA+AES:RSA+3DES:!ADH:!AECDH:!MD5"
no-loopback-peers
no-multicast-peers

Okay, thank you for your help. I will have a closer look in the next couple of days. If I am able to install coturn (I am not a professional), what must I enter in the Nextcloud configuration?
Is it only the server-IP or http://Server-IP or do I also have to give some port?
Do I have to enter something in the „TURN-Server Shared Secret“ as well?
I think that I can leave the STUN-Server (stun.nextcloud.com: 443) as it is, can‘t I?

I personnaly install a coturn on a External VPS for my own Nextcloud.
Easy to install, configure, use.
Therefore the begin was hard because you have to understand what coturn do and why you need it.
