ProGet $batch back Request

I am getting a bad request from the following path after I updated our internal ProGet installation to the current released version of ProGet 4.7.14

http://somefeed:81/nuget/feed/$batch

Please let me know what I need to do to fix this its not longer able to get this information from Visual Studio 2013

Product: ProGet
Version: 4.7.14

We no longer test (or have the ability to test) the NuGet Plugin for VS2013, as both the plug-in and VS2013 is no longer supported by Microsoft. That said, we haven't knowingly changed anything that would cause this to not work... but we will need quite a bit more details to understand what might have changed.

What version did you upgrade from?

What specific request used to work (from Visual Studio 2013 Plugin) that no longer does? Note you will need to use a tool like Fiddlr to capture this url.

Note that you will either need to downgrade to that version to identify this failed request that used to work... or install a second instance of ProGet of that Version for testing purposes.

With that information, we might be able to make a fix in a future version that addresses something that changed.

The version we upgraded from was 3.8.6
I listed the Fiddler feed its was http://proget:81/nuget/Devfeed/$batch
A page comes up with Bad Request

Now I am getting

401 - Unauthorized: Access is denied due to invalid credentials.
You do not have permission to view this directory or page using the credentials that you supplied.

More Data from Visual Studio after the Unauthorized, we got this:

--batchresponse_922c91ce-3549-41be-a150-e3f4659c2a2b--

Unfortunately there's nothing for us to go on here; with the limited information we have here, everything appears to be fine (the 401 is to be expected when you have an authenticated feed).

Because you're using the unsupported VS2013 NuGet Plugin (which we cannot test with), and you upgraded from an a two-year old version of ProGet with a ton of changes between, we have no idea what is going on. We would need to know precisely which requests worked before (request/response), and precisely what it's doing now.

Otherwise, you should just consider rolling back to 3.8.6 until you can upgrade to a supported version of Visual Studio.
