You can use a vpn or proxy like Psiphon and go to asset store.

if you want to upload a package do below steps:

1 - Go to Environment Variables (Right Click on your computer then choose properties then go to advanced system settings go to advanced tab and click on environment variables…)

2 - Add two variables

2 - 1 - Name: HTTP_proxy - Value: port here)

2 - 2 - Name: HTTPS_proxy - Value: port here)

3 - Restart unity
