When I connect to the server, it starts downloading the map as seen here: https://puu.sh/JL7q2/2f92cd74b9.png

Then it disconnects me with this message: https://puu.sh/JL7qj/3f5a5e64bd.png

What does this mean? How do I fix it?

I tried validating game files already.

This is the server IP: 31.186.250.21:27019
