Hello Marius,

IMPORTANT

Please go to the NuGet Keys page in your Telerik Account and delete your NuGet API key, because you exposed it publicly in this forum.

Then, generate a new NuGet key and use it instead. The problem was that you were using a NuGet API key together with your email as a username. The correct approach is to use a NuGet API key with "api-key" as a username.

Regards,
