I have a rather odd problem.
My nextcloud talk app cannot establish a connection with another person when calling.
I have installed a coturn server and the connection check indicates that it works.
I also have tried it from many other locations and network but the issue is always the same. I can establish a connection with firefox on the same mobile device or using a hotspot from the mobile device but i cannot establish a connection with the nextcloud talk app itself.
I see that it is working cause if I press call it imminently rings or if i want to make a call it immediately shows up in the browser. But there is only the spinning and it never really establishes the connection.
With firefox this works in seconds.
It also works with any other device except the Nextcloud Talk App on mobile devices.
I really are out of ideas what this might be cause I waited for the new version and check again but the issue remains.
What is different between the app and Firefox on the same mobile device?
Am I missing any obvious settings and never stumbled over it?
I had exactly the same symptoms with my installation.
For me updating the Android Talk App to the latest pre-release version (11.2.0 RC1) did the trick.
Since you did not share much information, I can’t say if our setups are comparable. I have coturn installed on the same server as nextcloud. The instance is hosted behind a NAT router. I was able to use talk via browser on all internal and external devices.
I understand that I am sparse with information and I will go a little into detail:
I use ipfire als firewall and reverse proxy with nginx and NAT to coturn.
All Domains used are subdomains with a lets encrypt certificate.
Coturn is installed on the same machine where nextcloud is installed only using another physical LAN connection with a different ip address.
The talk app has browser version 11.1.2 and the talk android app 11.1.0.
I use apache2 nextcloud with latetest version on a debian 10 system.
Indeed this is tricky cause I do not have a “working” system I can compare to.
I do not want to connect directly nextcloud to the internet and see if that works.
Well at least not yet if there is still hope.
