I saw that my server wasn't 1.18 and wanted to update it. I made a Backup of the world and updated the server to 1.18. I tried to enter the server but it wouldn't let me, first saying couldn't connect then just sending me to the lobby every time I tried to enter it. Now i changed the server back to 1.17 and restored the backup to the server and i still can't get into my server at all, anyone know how to fix this?
