I successfully started McMyAdmin on AMP, and it runs the server fine. However, when I try to connect with my Minecraft client, I get "io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection timed out: no further information". The server appears to be OK, since my ping is at 3ms and the server MOTD appears. When I click Join Server, it gets stuck on "Connecting to Server" for about 30-60 seconds, and then I get the AnnotatedConnectException message.

I have triple checked that both the network and computer firewalls allow two-way traffic through port 25565 for the game server and port 8080 for the webserver. I don't have any antivirus, VPN, proxy, or game enhancers enabled either. The weird thing is, I can connect on every port EXCEPT 25565. In the log, you can see that I tried changing the server to port 25566 and 8090. After I port forwarded, both of these ports worked, and my client was able to connect with no issues. It's only on port 25565 where I get the error. I tried resetting my router, completely removing and reinstalling AMP, flushing my DNS, disabling all firewalls, restarting the computer, and reinstalling the game. None of these have worked.

Details: Running AMP Hawking Starman 1.7.4.1 with a McMyAdmin Professional License, Windows 10 x64, UAC Enabled, latest Java version, and full administrator access (but not on the default admin account). Server is PaperSpigot 1.13.2, no mods.

This is the latest AMP log:

Any help is much appreciated.

Only on port 25565, the client gets stuck on "Connecting to Server" for about 30-60 seconds, and then displays:

io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection timed out: no further information

As for the AMP log, there doesn't seem to be an error other than

[Minecraft:Admin Warning] : The jar file you are trying to start is owned by DESKTOP-ETUT94D\Testing, but AMP is running as NT AUTHORITY\NETWORK SERVICE which may prevent the server from starting - you should use the AMP file manager to add files to your server to avoid permissions issues.

In that case your firewall rules and/or port forwarding rules aren't setup correctly. You can use netstat locally to check if it's listening.

If you can connect from another machine on the same network, the issue is with your port forwarding. If you can't, then it's a firewall issue.
