"Wrong server Region" - Private servers not working

[Prosnype]

Whenever I host a match, none of my friends can actually join, despite all of us having the exact same region. No matter how many times we tried hosting a match with different people (with some people having the demo and some having the premium edition), the game keeps stating that it cannot join the server possibly due to a "wrong server region", even though we checked that our regions matched multiple times.

Oh, I think it could be that you don't have "Allow demo players" option selected in lobby options? Right now free players will be limited to same game modes(this will change this Friday, Oct 1st)

If that's not the case, that's weird and I'll look into it. A solution for now could be to change it to public and have players join that way, then just turning it back to private after everyone joined.
