What exactly is the issue?

[G3NETIC]

Server is working fine, i just want to get rid of the errors from console.

[TileEntity]

Most errors are from betterx - maybe contact the creator

Looks like this mod is looking for a fabric.mod.json in each mod - but not every mod contains this file

The rest are recipe/advancement errors - these are common and can be ignored - mods making changes at recipes/advancements

[G3NETIC]

Okay, is there any mods that are client only? I can't tell.
I think that they are making some errors and slowing start of the server.

Today showed this error, full console spammed with this error
[Server thread/ERROR] [co.lo.st.StorageNetworkMod/]: Error thrown from a connected blockjava.lang.NullPointerException: Cannot invoke "net.minecraftforge.items.IItemHandler.getSlots()" because "inv" is null
- i know what it is

Also iam getting these warnings/errors, sometime. 
[12:19:49] [Server thread/WARN] [minecraft/ServerGamePacketListenerImpl]: Vaniilka moved too quickly! -14.216683168855525,145.5,-34.87110462073565

This warning is because of slow HW? CPU use is sometimes at 80-90%.
[Server thread/WARN] [net.minecraft.server.MinecraftServer/]: Can't keep up! Is the server overloaded? Running 2012ms or 40 ticks behind

The Can't keep up Message is also common and always pops up while discovering new areas or similar - chunk loading always causes some lags - this message just says the server is lagging

 

For the other 2 - I have no idea

Okay.
Many thanks!
