I can only host 2 specific servers on 2 specific ports
I have 2 separate servers running on ports 25565 and 25566. They work fine. After updating the jar of the 25565 server, players outside the network can no longer connect to it (but I can locally). I tested it out, and not only are no other servers hosted on 25565 (one at a time, of course) available to the public, but no servers are accessible via any other ports. I have verified all relevant ports are forwarded correctly on the router (and they have to be, because the original 2 servers still appear perfectly fine to players). I have tried hosting multiple types of servers (paper, fabric, velocity) on multiple ports to no avail. I am completely out of options, I have absolutely no clue what is going on.
