I play on Hypixel using some mods, so I use Forge for that. I have an epic gaming session for like 30-40mins and then I get kicked with following messages:

These tend to vary a lot, but it seems that it always has the part: "Internal Exception: io.netty.handler.codec.DecoderException:" I have tried playing with Vanilla (no Forge) and everything was completely fine for like 3-4 hours, so I can verify that it only occurs on Forge. I am also pretty sure this started happening to me the night after I updated Windows and used KMS hacktool (well I live in Russia, so we cant like afford normal license). 


I wish you could help me guys with that.

 

This issue is really annoying and I am fully committed to providing you with any additional information if you want to try to help me.


Ok so, to knock off obvious answers to fix it I tried: completely reinstalling Minecraft, rebooting my PC, restarting my Wi-FI router. As you can see from the ways of me trying to solve it, I am not the sharpest tool in the shed.

I am also fairly new to forums, so let me know if I did something wrong and how to improve

To maybe give you guys something to work with I can provide logs, but I can't figure out how to do it using pastebin. It has a limit of 512Kb of text, but mine is quite a bit bigger.

I tried setting up Google Drive, but idk if it works for you
