Github copilot activation woes in Visual Studio 2022

I got Copilot to work immediately in Visual Studio Code but on the same laptop can't get it working in Visual Studio 2022. I installed the extension and when I restart VS22 and load a project I get the messagebox from Copilot to connect with the activation code procedure. Clicking OK however results in the following in the output window (pressed the button a seconde time when the messagebox appeared again):

I've been searching around and tried already to flip Options > Github Copilot > Accept non-trusted certificate authorization to True. However still without being the solution.

Anyone facing this and, hopefully, has a workaround which works?

The solution was to follow the steps mentioned in this answer: https://github.com/orgs/community/discussions/50484.

Basically it turned out that netskope was in between for traffic and that the certificate needed to be added on my laptop with the command:

setx NODE_EXTRA_CA_CERTS "C:\temp\caadmin.netskope.com"

after I had saved the certificate caadmin.netskope.com under c:\temp.
