Hello.

Pretty sure I’m doing something stupid, but I can’t find it.

I have Caddy and Uptime-kuma installed as Docker containers. They are on the same Docker bridge network. Both work fine (with the below exception).

I’m trying to monitor Caddy virtual hosts from Uptime-kuma and getting a timeout.

If I exec into the Uptime-kuma container, I can ping the host name I want to monitor (and the DNS is resolving correctly to the Docker hosts external IP).

But I can’t reach port 80/443 using telnet or openssl.

Any suggestions for what I might be doing wrong?

Thanks!
