Task sequence software updates hangs downloading

Hi all,

SCCM 1810

I'm trying to deploy software updates including third party updates to task sequences, and the computers show downloading x from y and do not continue.

Right now I have a test VM that is stuck like this for more than a day. When I checked  the cache folder it did downloaded the x updates that are displayed on the screen but it doesn't continue.

I searched google and tried several suggestions but no luck.

Any help would be appreciated
