Player kicked, their protocol is 2177 not 2180Not An Issue

Getting error:

Kicking 196.112.66.178:62290/76561198873889880/KaSeR - their protocol is 2177 not 2180

How do I fix, thanks!

The player is outdated, they need to update their Rust client.
Ah. Thank you, was wondering why I was getting this error yet the plugin was still working... Lol. My bad!
It isn't really an error, it is just a kick message to a player. Not from or related to any plugins either.
Sounds good to me! Thank you for your swift reply! :)
