Can't join server(s) due to non existing map mismatch

There have been quite a few servers that I’ve been trying to join lately and it doesn’t allow me to because it says my map differs from the servers. I’d be fine with this and delete them if they existed, but I don’t have any of the maps downloaded. So any ideas what can cause this and how it can be fixed?

Which folders are you checking?

maps and download/maps

Try putting -noaddons and -noworkshop in your startup parameters. Also, delete your server GMA downloads.
