I can't get into ANY of my own servers even if my friends can.

This wouldn't bother me as much if I didn't literally pay for a server slot. It either says "can't resolve hostname" or I just stay in the lobby for an hour straight trying to get in.

When you try to join it from the lobby, does it say any messages about it? Also, if you started up the world from the lobby, i suggest running the command. "/join [servername]" roughly 10-20 seconds. after first typing it (to start it up).  You should also check and see if you are whitelisted or not.

Also, was this always an issue? or did it start happening only recently?

Make sure you are using the right ips to join. The direct ip is servername.minehut.gg and the lobby ip is just minehut.com. Say your server name is nerd, the direct ip should be nerd.minehut.gg.
