1.12.2 server and suddenly all chests and signs became invisible. the outline of the blocks still exist, and once u open the invisible chest, the chest comes back but the items that were previously there are gone. I have no clue what caused this.

Can we please get some professional help it has been 5 years and still this issue is among us.

Is there a way to look into the code or something to see when this error occurs and for what reason it gives that output?

Maybe this means something? Got the error and this is my server console: 

[02:04:53 INFO]: Pie3 lost connection: Timed out
[02:04:53 INFO]: [-]Pie3
[02:04:53 WARN]: handleDisconnection() called twice

[-] pie3 is custom log out message

this is happening to players on my self-hosted server, especially a certain world.

mabe this could help? someon crashed and it logged it on my console (ign: guccigang1) https://hastebin.com/uwonugucis.md

I have tried absolutely everything in this thread, nothing has worked thus far.

This issue still occurs on all minecraft versions.

I am certain it has something to do with the router, and could also be a minecraft bug that is fixable.

As far as I know, this occurs randomly, and I cannot find a correlation between anything that causes this issue. 

I was on a server with 2 different accounts with 2 minecraft windows. 1 account crashed to this problem and the other account I could play on perfectly fine. I could not play the server with the one that crashed with the same error after many tries. After I disconnected with the working account, it wouldn't let me play on that one either. This is a very odd problem and I still question whether it is due to router problems or based on client or server side.

Meep Games I have also tried the solution and it doesn't work, even with both public and local enabled.

I have noticed this is happening to me every single day on a certain time range, in my case usually around 7 PM to 11 PM. It kicks me from all servers after letting me join and render out people who stand still. Some servers kick me instantly, while others I can play for 5 minutes before getting kicked, depending on how good their host is.
This is definitely a problem with my internet or router, but I cannot figure it out, I have tried absolutely everything I could think of, and if anyone has ANY suggestions, I would be very grateful in a step forward to solving this.

This is very devastating and I cannot play any of my favorite servers and have no means of playing mc. Sometimes it works for about an hour and then the problem starts again. Someone please help solve this issue.

Hello I have the same exact problem, and none of the servers 1.12.2 work for me, only for 30 seconds of no interaction, and rendered chunks, then I get kicked for this error message.

My guess is that it has something to do with the router, everything else that I tried does not work.

EDIT: seems to be the case, it is the internet. I switched to 2.4 from 5.0 and i dont get the problem any more. It has something to do with the internet.
