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).
