Cannot restore package using ProGet feed with FindPackagesById()

I've recently installed ProGet. Using the latest version of the NuGet command line client (3.4.4.1321) and ProGet (4.1.0 beta), we have a package 'foo' with a version '1.10' that ProGet is not exposing to the NuGet client during a package restore of a solution. The NuGet client tries a bunch of different ways to download it, but they all return 404:

> nuget restore path\to\solution.sln

It was my understanding that ProGet implements the NuGet v2 feed protocol -- but it seems like FindPackagesById() and the Packages(Id=) syntax is not supported. Is this normal?

Product: ProGet
Version: 4.1.0

Hi there, based on the error I'm guessing you specified an incorrect feedsource of http://nuget.ourserver.com/

It should be http://nuget.ourserver.com/nuget/FeedName

Aha! Thank you! I didn't realize the feed wasn't at the root, since normal 'nuget push' and 'nuget install' commands worked with just the root URL as the '-Source' parameter. Only the 'nuget restore' failed.
