New installation self hosted on UBUNTU server 18.04 and forward 443 (TCO and UDO) and 10.000:20.000 (UDP), but error

Hi, I am trying a new installation, with dynamic IP fix,

The installation ends fine, no errors in terminal, I can log to the server typing and lands correctly on the Jitsi homepage. Camera and MIC working, but when somebody external joines the meeting, the meeting crashes.

How to debug?

Are you behind a NAT? Do you have the ports forwarded (please see guide) correctly in your router for this? Please check the quickinstall guide on how to configure behind a NAT

Are you doing this within the network?

Please post you jicofo logs. it can be found in /var/log/jitsi , mask any personal info
