Client Pauses After Map Download

Hello! I’ve got a little problem.
I’m setting up a Garry Mod server (Listen) on a custom map. A friend to join me, he connects fine, downloads the map. But then it says Missing Map.
Notes: Remote people can join when they have the map.

Do you have any type of fastdl server configured? What is your “sv_downloadurl” variable set to? Is sv_allowdownloads set to 1?
