Howdy @ArduFish123,

I was able to connect to your Caddy server on port 80, but the HTTPS port timed out.

I’d advise taking another look at your firewall; working HTTP implies your DNS is configured correctly and there aren’t any other transmission issues, but a timeout on port 443 implies that this port specifically is still blocked or improperly forwarded, either at the router or the individual host level.

Thank you, the port forwarding was not set up on port 443.
