Problem with packages manager

i have tried everything but i can’t finish it

hi @Erfan_Hasan Check if your firewall is preventing access to that server.

actually, it seems something different reading the message again.
@will can you inform how to resolve this?

I’d bet that it would still be helpful to Will to know whether Erfan can use a web browser to navigate to
Expected: getting a little notice about what version it’s running.

I am using Rhino-BETA. actually, I want to use Grasshopper 2 alpha, that why I was trying to access the package manager

I have solved that problem; the problem was with my internet, thanks for the support
