Mod maps not working

Everytime i try to use for example american road map for my server, it gives me a error map americanroad not found.
It doesnt give me the error with west coast usa winter, pikes peak, gull coast. I really want to play with my friend on some of these maps.
Please help!

american road is called “mymap”

So in the server config put mymap instead of americanroad

Thank you so much!
