Hello
I wanted to use this filter for Rejecting Connection, but it looks like the filter doesn't work for this.
I'm using version 1.1.0 for Minecraft 1.12.2

Configuration file

general {
# Any console messages containing one of these strings will be hidden.
S:messagesToFilter <
Rejecting connection
Itemy na zemi budou
This server has mods that require
>
}

Sorry, that console log is just picture, but I can't copy from it on the hosting.

Let me know if this is fixed as of version 1.12.2-1.1.1.

Sorry for the late respond.
It is not working for Forge informations. :(
