Cannot install VCode IDE on Mac HighSierra

I would like to use the Visual Studio IDE for PlatformIO but I am already stopped at the installation of the IDE package. Its an error from the Python pip installer:

PIP: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by ‘NewConnectionError(’<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x10ef1c9d0>: Failed to establish a new connection: [Errno 64] Host is down’,)’: /platformio/platformio/archive/

I have Python 2.7.12 installed via Homebrew, I can use pip with any other installation just fine.
I cannot find a real log window in Visual Studio to give me some ideas about the cause. Is this IDE using my correct python installation?

Thanks, Michael

Ahh, problem solved by myself due to a stupid firewall setting…
