I have no idea what it could be :\

[warjort]

One of your mods is trying to load client classes on the server.

The incomplete log you show doesn't identify which mod.

 

You probably have one the badly coded client side only mods installed? You can remove them from the server.

Rubidium, Oculus, Not Enough Animations or Legendary ToolTips are the usual ones reported, but there are others.

 

If its not one of those mods and the logs/debug.log doesn't give any further information then you will need to experiment with removing mods until you find the problem mod.

Backup your world/save before removing mods.

I will use your tip, thank you very much, I assumed that the matter is in the client-side mode, but I do not understand which one!

[yoru]

First I will start with client side mods, see what is the matter, I can also send full server log if it helps the case :0

Deleted oculus and rubidium mods from client mods, and its work! Pretty appreciate for tip!
