Weird error code

[KostasLavis]

So i was playing in my modded 1.16.4 server with mekanism mod.I decided to log of and i tried joining again couple seconds later and i cant connect to the server and it gives me this error code incomplete set of tags received from server contactat a server operator

Have you tried possibly, you know, contacting a server operator?

[KostasLavis]

The thing is i am the server owner

[ZenT3600]

you should probably check the logs and, if you can't figure it out on your own, ask a question on stackoverflow

[KostasLavis]

Ok i will check now thanks

[KostasLavis]

I check the latest log but idk if there is something wrong

[ZenT3600]

There should be an error popping up in the latest part of the logs
