Minecraft: Common Disconnect - Error Message: Internal Exception: java.io.IOException: An existing connection was closed by the remote host. What to do?

When I join joine on some server in Minecraft I often fly, usually after some time, with the error message: "Internal Exception: java.io.IOException: An existing connection was closed by the remote host" from the server.

I've already tried a lot to fix the constant popping error, such as. Minecraft to reinstall, the modification I used to reinstall, Java update, reboot router and and and…

I usually use the Mod, LabyMod "for Vanilla or Forge along with other mods like Schematica or WorldEdit, but I just tried it in normal vanilla without LabyMod, so I flew from the server as well.

I would be very happy to receive a helpful answer.

Sometimes the error occurs when the server is closed, but one is not kicked properly, but rather austimed.

But I assume that this is not the case with you, that all servers are always stopped. Then it's either on the server or on your internet.

The IP you have already changed, by the router reboot, right? Hmm okay, very interesting. Maybe you have the opportunity to test it over another internet, e.g. Set up a hotspot with data volume from the phone. It would be nice to know if it works or not.

If so, is probably because of your Internet, because you have to maybe again look at the router settings.

If not, it's probably on the server, it's best if it's your own, support from the hoster, or if it's different, contact Devs / Owner or the forum if they have one.

Thanks a lot for the tips. I'll try it the way you suggested.
