Kumasasa, I believe this might be an issue with the server software

itself. I myself just started encountering the issue as of yesterday with our 1.13 server. We have played many servers on the exact same machine on the same network and everybody has no problems joining other servers on the machine, but many people are encountering "timed out" and "An existing connection was closed by the remote host".

Firewall opened for the new server.jar?

The system is running Ubuntu Server LTS (18. whatever) with iptables that accept everything in every direction. We have tried messing with the router's firewall as well with no success (disabling it did nothing). The MC logs don't seem to agree with what they are telling the clients which is very strange. There is nothing that we've found in linux networking logs either. I have no idea what else to try, but it seems to be the new version of minecraft.

Kumasasa, the biggest problem we have encountered so far has been inconsistency in these issues. One moment somebody can play, and then next moment they get one of the errors above. It's very strange and we've completely run out of ideas to try.

Did you contact tech support?

Cole Abbeduto 2018-07-21T22:25:18Z

Kumasasa: Tech support who? You guys don't offer server support and this is my own server running on my own network.

Kumasasa: Yes, I've spoken to the IRC chat and only one guy suggested something and it was just firewall stuff which we already tried. It seems to be related to loading terrain since that's where the logging in takes the longest and then will either let you in or remove you from the game with a "timed out" or the "An existing connection was forcibly closed by the remote host". We have gotten people able to join the game by lowering the server's render distance therefore lowering the amount of data it has to transfer. It seems as though in 1.13 the amount of time that is allocated before the connection is considered "timed out" has been decreased. It would be great if you could as least humor me and look into that when you get a chance to see if there is any truth to it.

My assumption would be that you receive "timed out" when your client decides it has been too long and you receive the exception ("An existing connection...") when the server decides that it has been too long.

What's your server startup script? Please post it here.

Cole Abbeduto 2018-07-22T22:28:04Z

@Kumasasa, it's about as basic as it gets

#!/bin/bash
java -Xmx4G -Xms4G -jar server.jar nogui

java version 1.8.0_171

kumasasa 2018-07-23T00:23:58Z

try with adding -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn128M

Cole Abbeduto 2018-07-23T05:10:36Z

@Kumasasa, I tried it and it did not fix the issue. Still nobody can join when server render distance is set anywhere above 12 (only some people can join above 12). Any other suggestions?

kumasasa 2018-07-23T17:30:15Z

Out of ideas.

@Kumasasa, As I already said, community support is useless. I've already tried many times and nobody has anything good to suggest. I'm running out of ideas here...

kumasasa 2018-07-23T20:17:29Z

Last resort: try https://discord.gg/minecraft (but don't ask me, I'm already out of ideas)
