The issue you are facing:
Since installing and connecting the High Performance Backend as per this tutorial:
(How to Install Nextcloud Talk High Performance Backend with Stun/Turnserver on Ubuntu – Markus' Blog)
i’m unable to setup calls. In the web interface the button is inactive (greyed out) and when i start a call via the Android App nothing happens on te receiving side.
Steps to replicate it:
- install and connect the signaling server (all settings seem OK)
- create a conversation
