MultiContainerApp Lab: getting "Unable to load the service index" error

Which lab is it that you're having issues with? https://github.com/docker/labs/blob/master/windows/windows-containers/MultiContainerApp.md

Description The lab is failing for me on this step: docker-compose -f .\docker-compose.windows.yml build

Error

Unable to load the service index for source https://dotnet.myget.org/F/aspnetcore-ci-dev/api/v3/index.json. [C:\MusicStore\samples\MusicStore\MusicStore.csproj

Steps to reproduce the issue, if relevant:

Follow the step from the lab: https://github.com/docker/labs/blob/master/windows/windows-containers/MultiContainerApp.md

Describe the results you received: On Step 9, I got this error:

Step 9/15 : RUN dotnet restore --runtime win10-x64 .\samples\MusicStore

ERROR: Service 'web' failed to build: The command 'powershell -Command $ErrorActionPreference = 'Stop'; $ProgressPreference = 'SilentlyContinue';
 dotnet restore --runtime win10-x64 .\samples\MusicStore' returned a non-zero code: 1

Describe the results you expected: I expected the command to run successfully.

Additional information you deem important (e.g. issue happens only occasionally): I also occasionally got another timeout error on earlier steps of the same command (for example on step "COPY version.props ."). However, with re-running, this error will go away.

ERROR: Service 'web' failed to build: hcsshim::PrepareLayer failed in Win32: This operation returned because the timeout period expired
