Video and Audio lost with 3 participant (Subdomain & Apache)

I have a fresh install of jitsimeet with the famouse 3 participant problem. Read lots of posts to see what could be, but couldnt find an answer yet. Thanks in advance!

situtation:
2 people work fine, but as soon as one more joins and switchs to videoBridge, the video and audio stops working.

Server:

  • UBUNTU 18.04.4.
  • Direct access to Internet (not using NAT)
  • Firewall ports enabled: 443, udp10000, tested from (https://check-host.net).
  • Apache as webserver, and jisti in subfolder “meet” working correctly.
  • External IP visible in setRemoteDescription -> chrome://webrtc-internals/

Console JS repeats constantly says:

  • 020-05-07T23:27:15.896Z [modules/RTC/BridgeChannel.js] <l._send>: Bridge Channel send: no opened channel.
