1. The problem I’m having:
I’m trying to run a home server to host a media server, a teamspeak server and a minecraft server. I’ve got a custom domain through cloudflare so friends/family will be able to access these without having to connect through a direct IP. I have managed to get all of these running and accessible through a direct IP connection, however I’m struggling with the Caddy setup.
I have a separate cloudflare DNS record for each, but they are all configured the same way and point at the same IPv6 address. I installed the caddy version with the cloudflare extension because at some point I thought it would fix my problems but now I don’t know if I needed it or not. I also have the cloudflare key hardcoded in the config file because it did not want to load the environment variable, but that is a problem for another time.
Here’s my problem: Despite using the same config the media server is accessible through the custom domain but the teamspeak and minecraft server are not. Teamspeak and minecraft both don’t give any useful errors.
I see “HTTP/2 skipped because it requires TLS” in the logs and I wonder if that is relevant, but if it is I can not figure out what to do about it.
I am very much a noob at this but I’ve spent 10 hours trying to figure this out and I am at the end of my google powers, any help would be very appreciated 
(also, please let me know if caddy is not the right tool for this)
Thank you
