Steinberg Activation Manager doesn't connect to internet


I am trying to activate software ( Cubase, Dorico, …) on my MBP. But when I run SAM and click on Sign it, nothing happens, I get message:

Any ideas?

PS. Obviously I am connected to internet posting this!

The “sign in” button should open a browser window or tab.
Maybe your MBP is blocking this.

Thank you. I just checked my connection, for some reason, my proxy was turned on!!
