Caddy Server Listening Port AIRVPN issue

Ok, so this is really weird but here it goes.

:2015 {

}
force quits caddy server.

If I take the VPN down and put
domain.duckdns.org
proxy /sonarr 192.168.1.253:8989

it works from inside and outside my network at domain.duckdns.org/sonarr

Ok great, right?

Now if I put domain.airvpn.org caddy server immediately shuts off and won’t stay running. The cmd window pops up says activating privacy features then immediately shuts down. I also tried running as administrator and got the same thing. I swapped out the two domains multiple times with the same exact effect. Caddy Server refuses to stay running with domain.airvpn.org

Weird, right?
