After starting my vanilla server (0 plugins/datapacks/etc.) I start playing for like 4-7 minutes and this error appears: "Internal Exception: java.io.IOExpection: An existing connection was forcibly closed by the remote host".
I restarted the server....same problem, friends are getting same problem while in the server, everyone has 100mb/s+ internet.
