MC-265798

The error: "Internal Exception: io.netty.handler.codec.DecoderException:java.util.zip.DataFormatException: incorrect header check" is posing a consistent problem.

The message appears every time that I try to enter a Minecraft server on multiplayer, but it is actually on version 1.20.1. I have tried turning my render distance to 2 (older recommendation), resetting the game and my launcher. Later I would take my account off of the launcher and add it back on to no prevail. I have seen other posts about this problem but much older versions (1.10/1.13) but no solution for nowadays.

Any help is appreciated!
Thanks.
