Garrys Mod 13 Server Addon Problem

Hello guys, so i was tryieng for hours to fix this, and havent got a solution yet…

I am hosting a gmod server with the scrds thing, everything works fine, addons are in it via the steam workshop collection “mode” and they are working for me, because i (obviously) had to download them.

But my problem is, no other player who joined had to download them, and so they only see errors :c

Ive tried everything and i have no damn idea what to do know -.-

Setup a fastdl

fastdl isnt working… i have everything in the lua in autorun and the webspace is working to, but nothing is downloading
