TeamCity NuGet: packages visible but not downloadable

We are having trouble with setting up deployment from a TeamCity NuGet feed. It worked fine with version 1.6, but not with 2.0.

The weird thing is: after entering the feed url and credentials, we can see all the projects in the feed, but during a deployment the following error occurs:

Unable to download package: The remote server returned an error: (403) Forbidden. System.Net.WebException: The remote server returned an error: (403) Forbidden.

Thanks for getting in touch. Are there any clues in the Verbose (or Raw) view of the task log?

Can you also please let us know which TeamCity version you’re using?

Regards,
Nick
