Netty Worker IO Thread #7

Hello.

I made self server cluster with few minecraft servers.

I create 2x spiggot and one moded server (Sky Factory 4 with sponge).
I use iPortal and waterfall, with 2 spigot servers all works nice.
When i connect SF4 server i get logs:

[01:01:13] [Netty Worker IO Thread #7/INFO]: [kretowicz14|/192.168.90.10:65236] <-> ServerConnector [sf4] has connected

Do you have any idea how to debug? Also command /server sf4 dont help :confused:

I can reply myself.

Problem was sponge configuration base.conf where i enable only one option.
