Does anyone already experienced this problem?

@kesso1 It seems like the machine in question is not able to reach the revocation server.

Can you run the same thing under fiddler and see which calls are failing?

[aortiz-msft]

Hi there! We will be closing this issue since we haven't heard back since the last comment from @nkolev92. Please feel free to comment or open a new issue if needed. Thank you for your feedback.

The same issue with packages. Seems like the signature certificate expired today:

So people around the world can't even compile their code because some random employee at MS forgot to renew their certificates... what a terrible ecosystem. I just bumped into this issue today trying to compile osu!lazer.

Also seeing Nuget errors for all packages in a repository. Has started happening out of the blue today (27/01/2021).

Yeah, this really is a random incident.
