Describe the Bug

When logging into the server it will go connecting to server --> logging in ---> then encrypting until it times me out. The console gives me this error when I try to log in

05.07 18:53:02 [Server] Netty Epoll Server IO #7/ Login payload for Registry minecraft:item is using 27.1971% of max allowed vanilla size
05.07 18:53:02 [Server] User Authenticator #9/INFO UUID of player ShortRound1360 is 20b982ad-8e56-4b7f-b554-3e333186fd15

I've never had this problem before and there is no clear reason as far I can see, it was working just fine the day prior and even though I did nothing, it broke
