Video-Cam and Screensharing not working - Media Server Offline 2001

[Xaver2k]

Hi, i finally got the bbb-docker kind of working, but Video Cam and Screensharing is not working and shows "Media server is offline. Please try again later (error 2001)"

My Server is running Plesk Obsidian Version 18.0.30 and the Docker extension, i used Docker from SSH to set everything up.

At the beginning even Audio was not working, but i got it with the correct firewall rules to allow traffic on all ports from 10.7.7.0/24. I Already tried to Allow all Incoming and Forwarding traffic without success. And i needed to add following additional NGINX directive:

location ^~ / {
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    proxy_set_header X-Frame-Options SAMEORIGIN;
    proxy_pass http://SERVER_PUBLIC_IPV4:8080;
}

IPv6 is not working/setup on the server, mandatory or do i need to disable it somewhere?

Any suggestions here??

Thanks in advance

I got it working Port 8888 for Kurento Server Container was used by another application... and i had a typo in my grep regex so i couldn`t find anything and thought the Port is free. Killed the application that was using the same Port, restarted the Kurento Container and now it works! I ended using this, to check if Port is free

netstat -peanut | grep ":8888 "
