Maybe a rendering issue with SodiumExtras

Delete the curios-server.toml file in your config folder

Add client and server log after such a disconnect

If it is no lagging ingame, you can ignore this message

And without LMFT?

And does it have a server pack?

Looks like an issue outside of Minecraft - some kind of Network issue

Add the full log

Remove lithium or modernfix

Also remove sodiumdynamiclights from the server
