Since NC16, I am facing to audio / video and turn issue
1: My complete configuration:
Nextcloud 16.0.0 on a dedicated server (192.168.1.100 on my local network). For tests, UFW is off
Coturn 126.96.36.199 installed on a “service” server (192.168.1.200 on my local network). UFW is off too.
Both servers are ubuntu 18.04 servers
Port forwarding on my network: 443 on 192.168.1.100 (for NC with ssl access)
3478 TCP & UDP on 192.168.1.200 (for stun and turn access with no TLS)
2: my turnserver coturn conf:
static-auth-secret= #generated key with openssl command: openssl rand -hex 32
realm= #my external internet box fix IP address
stun access is ok through website Trickle ICE https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/
Tested : stun:myexternalIP:3478 =>ok
turn cannot be tested without introducing the auth secret.
4: NC talk parameters
On parameters webpage, I have added stun server, it seems to be ok
when I add turn address (externalIP:3478 , auth secret key, TCP & UDP) I obtain a “!” flag error. So I removed it
5: communication tests
Mobile 2 mobile communication, with the last android app (6.0.3)
local network wifi <> wifi : chat, video and audio work fine
LTE <> wifi and LTE<> LTE: only chat work. Video and audio don’t.
6 : my questions:
I can’t see where is my configuration issue. Could you help me? a turnserver issue conf? a port forwarding issue?
Is there a link between turn issue and LTE communication issue?
