Metahuman not downloading behind company's aggressive firewall

I’m currently using Unreal and Metahuman Plugin within company network.
As they impose aggressive firewall policies, I had to request for network exception using following info.

-target url
epicgames.com

d2fnyr57rfiuz.cloudfront.net
ddinktqu5prvc.cloudfront.net
megascans.se
d3uwib8iif8w1p.cloudfront.net
quixel-mhc-assets.s3.us-west-2.amazonaws.com
quixel-apps.s3-us-west-2.amazonaws.com
quixel-megascans-assets.s3.us-west-2.amazonaws.com
quixel-megascans-assets-payloads.s3.us-west-2.amazonaws.com
quixel-mhc-presets-assets.s3.us-west-2.amazonaws.com
(TCP 80,443)

However, when trying to download custom metahumans that I created using Unreal Engine 5.2 and metahuman creator (website), the download within (Quixel)bridge in Unreal program progresses from 0% to 99%-ish and then resets to 0%.

Do I need to add other exception URLs or PORTS for this to work behind the firewall?

I’m guessing there’s some target URLs that says something about 'quixel-mhc-[MY_METAHUMAN].s3.us-west-2~~?

if anyone knows, some help will be appreciated.
