I recently made an account today and tried to make a modded server for my friends and i to play in. When I thought I had everything set up I tried to start the server to check everything was working, and it wouldn't start. I would click "activate" and the leftmost green option would say "activating" for like 30 seconds or so and then just go back to "offline". Whenever i tried logging onto the server I would get kicked into the minehut hub. I tried logging into the server from the hub, but that didn't work either. Any suggestions?
