Unable to restore Nuget packages from TeamCity Authenticated Feed URL


We have multiple C# Projects that require NuGet packages published to the Authenticated Feed URL of our TeamCity server.

In the past there where no problems in restoring packages from this feed using a NuGet installer build step with "%teamcity.nuget.feed.auth.server%" as source and "NuGet Feed Credentials build" features set.

I recently tried to setup another build configuration with the same build step and build feature configuration as any project before. But I get the following error message:

Bitte stellen Sie Anmeldeinformationen zur Verf�gung f�r: http://<teamcity-ip>/httpAuth/app/nuget/v1/FeedService.svc
UserName: WARNUNG: Im nicht interaktiven Modus kann keine Eingabeaufforderung erfolgen.

(English: Please provide credentials for: http://<teamcity-ip>/httpAuth/app/nuget/v1/FeedService.svc
Cannot prompt for input in non-interactive mode.)

Old configurations are still working, but I can't create any new without that error.

It seems to me that this problem occurred after upgrading to TeamCity 9.1.6.

I checked the TeamCity issue tracker and found the ticket: TW-42590. This seems to be exactly our problem, but it is reported to be fixed (Though the last comment states otherwise)?

Any advice on this problem would be highly appreciated!

Hi Norbert,

Sorry for delay. We reproduced the issue and created a bug report: https://youtrack.jetbrains.com/issue/TW-44438. Please watch to receive updates.

As current workaround you can try to use NuGet version 3.2.x.

Also please note that since TeamCity 9.1.4, when using TeamCity as the internal Nuget server, the credentials specified via this build feature are ignored; the internal TeamCity authentication is used. So you can remove "NuGet Feed Credentials build" feature from sever.

Thanks for the update.

I checked the ticked. I'm currently using NuGet 2.8.6 on the build client where it is not working. I'll try 3.2 as you suggested.

Hi Nobert,

Thank you for the details. We found a bug in 9.1.6, please see https://youtrack.jetbrains.com/issue/TW-44479. As workaround please specify the server ip address instead of using %teamcity.nuget.feed.auth.server% property.

Please let me know if it helps.
