Dedicated Server: Your map [maps/???.bsp] differs from the server's.

I run my dedicated server on Windows Server 2012 R2 x64. I can’t join to my server because the server believes that I have a different version of the map dm_crossfire. Help me please.

Your map [maps/dm_crossfire.bsp] differs from the server’s.

Why is this happening? Will there be fixed?

I don’t know whether these are stock maps, or downloaded from the Steam-workshop, or manually installed onto the server so…
Did you manually install the maps onto your server?
Did you manually install the maps into your own folder?
Is your server running a newer or older version?
Do you play with the latest update?
