Map problem help!

I changed my servers map to “rp_apocalypse”, but whenever a player that doesn’t have the map joins it gives them map is missing error. It is not just one player, they tried deleting it from their map and addons but it won’t download for them for some reason. Help me please!

Is the server set to actually autodownload? And is the map edited in any way?

Its fixed, i had to put it to garrysmod folder instead of addons
