Hi, I have similar questions.
What I’ve been wondering are:
- When I have to point the jitsi-meet server’s FQDN to the loopback address(es)
- Which processes (programs) require it and what do they use it for
- What happens without it
I guess it’s required only when the server doesn’t own an IP address associated with the FQDN (e.g. the server is behind a NAT and the address is actually owned or controlled by the NAT) but I’m not sure.
[EDIT] I briefly tested such a case on a containerized environment (FreeBSD jail) but it seems working without “127.0.0.1 FQDN” entry.[/EDIT]
It would be great if someone could answer those questions.
