Hi forum!
I’ve problems to get Nextcloud Talk running smoothly with High Performance Backend.
First my setup:
- Nextcloud 19.0.4, Talk 9.0.5 (also tested 20.0.1 Talk 10.0.1)
- Ubuntu 20.04.1 LTS
- janus gateway 0.10.5 (also tested 0.10.4)
- nextcloud-spreed-signaling version 9206a56113064b8e44b0de12d5128f8e88617679/go1.13.8
- nats docker latest
- coturn 4.5.1.1-1
- libSRTP2-1_2.3.0-4
I’ve setup the HPB with the tutorial from https://decatec.de/home-server/nextcloud-talk-mit-eigenem-signaling-server-high-performance-backend/
Here my problem:
The call is running fine until someone is starting to share a screen. From there all video streams are freezing till the screenshare is not stopped.
In signaling log i can see many entries like:
Nov 12 12:37:58 myhostname signaling[1789]: mcu_janus.go:1012: Subscriber _Tx-QfEhFjvhSFiOnUI2LZnFXscJY7RlRZiIkLepDgZ8aHVDRVotaG5SWkwwaVdYRkhDU0UyVVhXQ2ZhS0phcnFaVVFLdWcteU9maEN5S1VyRnJOeW9pd1l1Y0hPR0QwZlIzbEszd2Z6aUEweXh1d05YWXBGYVFoZlFkalN5b2x3ZHBkM2E5X1cwdkNBdDdaVHJ3ZHZMWTNMaWdlTXpkM01ZQnBJZkJNcTc4VVBWek1qWkdrV0ZQelJwcnpWeTZUYTRTQl95cDl4fDEwNDI4MTUwNjE= (5814447515383452) is reporting 39 lost packets on the uplink (Janus -> client)

All other log files are fine.
I tried a lot of stuff:
- disable ufw on signaling server
- allow all traffic between signaling server an internet (DMZ), no firewalling between
- test multiple browsers / clients
- client’s and server’s CPU/Network/Ram is easy going
