Is IPv6 supported?

[Zorro92]

I have uptime-kuma monitoring containers/web services. The replex container is called "replex" and so in uptime kuma I set the url to "http://replex/identity" but I get an error like
connect ECONNREFUSED fd00:IPv6::addr:80
Obviously with my containers IPv6 address. It fails to communicate but it can communicate just fine if I use localhost. All my other containers with fine. Is IPv6 supported with replex?

So if I route Plex directly I get valid addresses albeit ipv4 haven't been able to get IPv6 to show up directly yet but if I route it through replex it shows up with a unique local address. I'm confused as to why.

Ok so I actually fixed this by putting it on the same network stack using network_mode: "service:container" in my docker compose

Actually this still didn't fix my uptime kuma problem. It works if I do localhost:port but not container:port
As long as it works though that's all that matters
