hello, I'm trying to get jitsi-meet working @debian10 and ispconfig 3.15.p2. I followed the instructions from https://www.howtoforge.de/anleitung...enzserver-mit-jitsi-meet-auf-ubuntu-1804-lts/ , of cause with a little bit of modification for debian 10 (openjdk 8 isn't anymore supported) So this part went fine - jitsi-meet is installed, but when I create a new chat it disconnects me within 3 seconds and nobody can join my chat. Is there something which has to be modified? in ispconfig I've added a new vhost and created the lets encrypt certificates. hope anyone can help, thank you.
