FastDL not working or just slow ?

Hello , I currently am running a server and it has FastDL on it while also downloading stuff from workshop , and it takes players maybe 15-20 minutes to load into my server and apparently for some files the download speed is 30 kb/s . I don’t know what the problem could be and I was hoping someone could point me in the right direction for fixing this .

Can you post your server.cfg?

my server.cfg was correct , I found that the webhost just had really slow speeds and I’m upgrading to a new one , thank you for replying tho !
