Unable to create/expose new subdomain

[ElDuko (Lyubomir Penev)]

1. The problem I’m having:

I am running caddy as a reverse proxy for all the services on my home server and ran in to a problem recently when I tried to expose a new service, however Caddy appears to not be able to reach it. It is important to note I can reach the service using from my laptop.

2. Error messages and/or full log output:
