That's the error. That's it. One of my users can connect to any other server than mine, and when he tries to connect to mine he gets this error.

Internal Exception: io.netty.channel.unix.Errors#NativeIoException: syscall:read(..) failed: Connection reset by peer

This is so weird! Because in the console, all I see is this:

[22:18:30] [Server thread/INFO]: Bosscrafter73[/xxx.x.xx.xxx:xxxxx] logged in with entity id 380 at (14.5, 69.0, 253.5)
[22:18:30] [Server thread/INFO]: Bosscrafter73 joined the game
say hi boss
[22:18:39] [Server thread/INFO]: [Server] hi boss
[22:18:55] [Server thread/INFO]: <Bosscrafter73> testing
[22:19:01] [Server thread/INFO]: Bosscrafter73 lost connection: Timed out
[22:19:01] [Server thread/INFO]: Bosscrafter73 left the game
[22:19:02] [Server thread/WARN]: handleDisconnection() called twice

He doesn't receive the "hi boss", and when he said 'testing' he didn't recieve it back to him at all. It seems like he can send packets but not receive any. He was able to connect perfectly fine in 1.12.1, and then I updated to 1.12.2 and he can't connect anymore. What is going on??? This is what his client logs say:

Please help! We've been battling this for a month now, ever since 1.12.2 came out and I updated. This happens on a vanilla 1.12.2 server and a spigot 1.12.2 server (both). I host the server on Ubuntu 17.04 using OVH Services on Java 8 (And I attempted Java 9, same error).

Please, if anyone knows about this or can help us fix it please help. We really want him to be able to play the server, and it's beginning of effect other players as well. It's slowly taking over our server and soon nobody will be able to connect. (Bump)

This is slowly starting to take over our server and a lot of players are getting this error now, what exactly is going on? (Bump)

So nobody knows about the issue or any way to fix it. This is wonderful. Guess we'll just have to wait for the next version of Minecraft then. (Bump)

We've found it's related to internet speeds and anything below 2-4 mbps down and anything below 512 kbps up can cause this issue. It kind of fixed itself over time aswell.

Essentially: no
