I and a few colleagues have a minecraft server with which we play the Pixelmon mod and today the server is crashed and I and a colleague can't do it because we the message (io.netty.channel.abstractchannel $ annotatedconnectexception: Connection timed out: no further information) and we have minecraft already reinstalled server rebooted firewall turned off and much more and now I would like to reinstall the server so that we do not lose Pokemon and the world is saved and thus completely new is set up?
You have to download the world files. If you have any plugins, it would be useful to download the plugin folder.
Then delete the server and restart
