Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can :heart:

Nextcloud version (eg, 12.0.2): 16.01RC1
Operating system and version (eg, Ubuntu 17.04): KDE Neon (newest)
Apache or nginx version (eg, Apache 2.4.25): Nextcloud from docker 16.01RC1 with Apache
PHP version (eg, 7.1):

The issue you are facing:
Nextcloud Talk closes conversation after few failed attempts of signalling. There are 404 errors in DevTools. Server has configured custom TURN/STUN and video conversations between networks works great. Signalling server is missing in settings and I have no idea how to configure it.
The issue is a problem for publicly linked chats, where not technical users are uncommon with Nextcloud

Is this the first time you’ve seen this error? (Y/N):N

Steps to replicate it:
Open

  1. Nextcloud Talk
  2. Create public conversation, click link in Incognito Mode with Devtools opened
  3. Watch console for 404 errors.
  4. After message “stop pulling messages after repeated failures” chat closes. If it’s opened by public link, it redirects user to login screen.
