I have a build definition created in TFS 2017 and this build definition has a nuget restore task configured in it, which tries to download the newtonsoft.json 12.0.2 package from a private nuget respository of us but it fails to restore the newtonsoft nuget package and only restores the other nuget packages that are also mentioned in the package.config.
I have copied the log as well of the nuget restore task for reference.
