Many thanks for the reply. I have a VPS with a fixed IP. My provider claims that it it not behind a NAT and I certainly don’t have a private IP address. I tried getting Nginx to listen on port 443 rather than 4444, but the browser couldn’t then reach the server.
On this last installation I installed Debian 10, made no adjustments whatsoever, then immediately installed jitsi-meet. It worked in the sense that I could reach the server and start a session, but the problem of crashing described above was there from the first session.
I have since set the hostname to the subdomain name. I have pinged this hostname and it works. I have set all the ports as requested. ufw status reports as below and I’ve tested the ports with nc and nmap and they both report the ports to be working with the exception on 4443 where I get a closed error although a test with netstat suggests that the problem is that nothing is listening on the port.
I hope that you’ll be able to carry on helping (and help me solve the problem). As mentioned I’ve been working on this for weeks.
As mentioned I have installed various Debian/Ubuntu/Nginx versions configurations and I always have the same problem.
