    Hi:

    I am playing multiplayer version 1.16.4, until it started to go very slow and then I got this error when starting multiplayer, I saw on the internet that I should remove all my virus protections but I'd better ask first. It is worth mentioning that the server I did.



    I hope you can help me :saint:
