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!
