I have noticed that since upgrading to v5.3.5 Proget, the connector/nuget feed is not working properly. For example I am trying to download CommonServiceLocator.1.3.0.0.nupkg, it is an external package in the public nuget server. This is what i get when running in CLI
C:\Dev\Nuget>nuget install CommonServiceLocator -Version 1.3.0 -Source https://localprogetserver/nuget/ks-nuget/
Feeds used:
C:\Dev\NuGet\packages

Package 'CommonServiceLocator.1.3.0' is not found on source 'https://localprogetserver/nuget/ks-nuget/'.



In the pictures above, it shows that its clearly available online through the external connector.
Prior/ expected result when I try to install a nuget package not on our local proget server is that I get proxied out to the external nuget.org and get the installation.
Please assist.
