Minecraft Server Failed to connect

Question

I'm trying to set up a Minecraft server on a CentOS 7 VM so that my friends and I can play. I've been following a guide on how to set it up and was able to make it all the way through until the actual connecting to the server part.

I've made sure there is a port exception for 25565, and when I use ss -natu it shows the the port is listening for a connecting from java... though every time I try to connect I keep getting the io.netty.channel.abstractchannel$annotatedconnectexception connection timed out error.

Not sure if I don't have the firewalld set up properly or if something else is the matter.

Are you sure that the port forwarding works the same when using a VM? It might not appear as its own device in your router, in that case you might only grant access to the host system, not the VM. — Fabian Röling, Oct 03 '19 at 12:17
Sometimes the port forwarding on a VM may not be seen through the host machine. You can check quickly by performing a test with tools like canyouseeme. If the tool can see the server then the firewall is setup correctly. If not, then the firewall is an issue. — GipsyD, Jun 24 '21 at 11:29

I thought this would have been part of Is there a list of error codes for Minecraft?, but no. Should it be added? — Joachim, Oct 18 '22 at 06:10
@Joachim its quite common of an error, but there is another dedicated post we often point to (as pppery linked). — Timmy Jim, Oct 19 '22 at 14:24

Are you using bridged or NAT mode on your VM? Also, on CentOS, SELinux may be preventing you from connecting. Check out this link for instructions on how to work around that.
