I’m really confused with your logs..
you configure port :3478 in your server but test :3481 in trunutils?
work on one problem at time
- green checkmark doesn’t mean TURN works - it only means the server can access turn.. still each client requires access
- check each client one by one - for me best tactic is using a laptop connected to different network e.g. home wifi and mobile data - looking at firefox
about:webrtctells you which candidates worked and which not (or better if it successfully acquired TURN candidates)
