Players cant connect to my server after version update

I'm running a 1.14.4 paper server that I just updated to 1.18.2. NOTHING else has changed apart from this update, however players can no longer connect to the server from outside the network. Important things to note: - The server works perfectly fine connecting via localhost - When I switch back to the old 1.14 version, players can connect - Port checking sites say the port is open when using the 1.14 version and closed when using the 1.18 version - Console confirms the server is being hosted on the correct port I have no clue what could be causing this, any help is appreciated.

I'd like to reiterate that the port forwarding settings work. When booting the 1.14 install, players connect just fine using the same port. Also, I have 2 other ports forwarded to this machine whose services work fine

Check the port is the same for 1.18

Yep Update: I have determined that I can't host any other servers on port 25565 except for that one server, even though when connecting to localhost it works perfectly fine. I have tried restarting my computer and reopening the port
