Steps/models to reproduce

Stacktrace: https://pastebin.com/hQqbVRg3
I am not sure if this problem is reproducible, but I will post the work I did before the problem occurred.
1.Set "keep-spawn-loaded" to "false".
2.Set "view-distance" to "80"(This is because other players have told us that the drawing distance is too short).
3.Restarted the server with users joined.

Are you running this behind a proxy ?

I am not sure if it can be called a proxy, but I use a service called playit.gg.
