Ubuntu 20.04.1 LTS AMP Application Version 2.0.6.2 McMyAdmin for Minecraft Binding 127.0.0.1:8082 Endpoint 0.0.0.0:25566

The Minecraft server is up and running. From MCMyAdmin, I can run help in the console and get results. Logs show no errors.

12:00:17

Starting Server Version 1.16.40.2 Session ID 54c3f747-f09d-4767-9745-bc95d026b43e Level Name: world Game mode: 0 Survival Difficulty: 2 NORMAL opening worlds/world/db

12:00:26

IPv4 supported, port: 25566 IPv6 supported, port: 19133 IPv4 supported, port: 19132 IPv6 supported, port: 42541

12:00:29

Server started.

However I am unable to connect to port 25566 from the Ubuntu host itself, or anywhere on the network - get a connection refused.

25565 doesn't exist anymore - that was deleted, but the firewall entry was never cleaned up. That's not good.

I'm not seeing any blocks in the firewall.

Is the ampfirewall service running?

It looks like it finally added it, but now it looks like the port isn't opening on TCP4, only TCP6 for some reason.
