during startup it says:
```
Ignoring TLS-enabled STUN/TURN listener
```
and later
```
Invalid certificate in /var/lib/acme/uninsane.org/fullchain.pem: at line 61: certificate is signed by unknown CA
```
the invalid cert thing has always been here. it's for the root cert. idk
if i need to tell ejabberd that one's self-signed, or what.
discovery is probably not working:
```
Won't auto-announce STUN/TURN service on port 3478 (udp) without public IP address, please specify 'turn_ipv4_address' and optionally 'turn_ipv6_address'
Won't auto-announce STUN/TURN service on port 3478 (tcp) without public IP address, please specify 'turn_ipv4_address' and optionally 'turn_ipv6_address'
```
no messages for the TLS implementation, so maybe that's working?
i guess the cert already had that because of legacy prosody setup (?),
but we weren't setup so that new requests would work, i expect.
either that or all of these nginx entries aren't necessary?
- shorter.
- congruent with `nixos-rebuild .` choosing what to build based on `hostname`.
- more widely used within other nix repos i've seen.
- more accurate in the case that i migrate a host to a different
machine (which i plan to do with servo).
