Dedicated server. workshow downloads fail?

Hey guy’s. i’ve had this issue for a very long time and havent been able to find any ways to fix it after tons of googling,
basically, certain addons over a certain size seem to just stop downloading updates, and say download failed.
I have tried increasing net_maxfilesize to no avail (i’ve set it to 4096, which presuming this is in megabytes, that’s 4 gigabytes and far more than the file that’s failing.)
I’d see something like this in console

Download Failed!

It’s always this one particular addon, which leads me to belive its an issue with filesize, the only way i have found to fix this (kinda) is for me to download it on my client, rename it to ds_(insert addon id).gma and manually upload it
Is there some sort of setting i can use to fix this?

Is the addon you are trying to download bigger than 64MB compressed? Because if it is, that’s a bug with the game that you cannot fix.

net_maxfilesize has nothing to do with this, it is only revelant if you are using ServerDL, not FastDL or WorkshopDL.
