Adding OData Connected Service to the project failed: Unable to load the service index for source https://www.nuget.org/api/v2/.

Our enterprise network is isolated from the Internet.
My VS 2017 NuGet manager is configured to use only local package sources.

Now I have the subjected problem. I hope, that all needed packages are manually downloaded to the local storage. But this VS setting seems to be ignored by OData.ConnectedService.
P.S. My OData source is V3. Source code shows that V3CodeGenerator has completely different logic for package locating.
P.S. Locally I have:
microsoft.data.edm.5.6.3.nupkg
microsoft.data.edm.5.8.3.nupkg
microsoft.data.odata.5.6.3.nupkg
