Keep Getting Kicked Why I Try To Join A Wc

I dont see many other people complaining about this issue but its been getting worse, almost to the point where i cant play the game. Today i had to relof 23 times to actually play, and then got kicked like 5 minutes afterwards. These errors are always io.netty and "packet size -478174838729 is below server limit of 240" or something like that. How do i fix this? and yes before anyone shows me the salted pack fix i have tried that already.

 

allow java and minecraft through the firewall(private network access)

 

All errors i can find:

Internal Exception: io.netty.handler.codec.CorruptedFrameExtension: length wider than 21-bit

Internal Exception: io.netty.handler.codec.DecoderException: java.util.zipDataFormatException: incorrect data check

Failed to connect to the server
you are already logged onto the server

How?

 

k, go to taskbar and search up windows defender, open the first result click allow an app to communicate, and then click change settings at the top, then javaw and allow through private networks, and then java(TM) platform SE binary, and again allow through private networks, make sure to only allow private otherwise ur computer might get hacked

 

I dont see javaw but i do see Java(TM) platform se binary is that the same?

 

Java Platform SE Binary is the Minecraft application, so yes that is what you want to allow. If you open up the Task Manager, it is what appears when Minecraft is running.

 

yeah thats right

 

i was a bit confused because i was getting kicked again but when i checked it again it had two java platform and i hadnt checked one, so i did and it seemed to work

 

I am still having issues but theyre completely different error messages now and decided to check again and now there are four java platforms now, it makes a new one that isnt allowed every time i check it.

 

I have re downloaded minecraft and it is STILL HAPPENING! WHY?!?!?

 

from my experience, sometimes my router would randomly prohibit certain connections (idk why...), but resetting it fixed it. I suggest resetting your router by unplugging it for 10 seconds and plugging it back in. It's a long shot, but hope it solves your problem!
