`dotnet new` throws 401 unauthorized without version on package name

Question

So I have a dotnet template that is published to nuget, but it is only getting installed when running the install command with the version like so: dotnet new --install Foundation.Api::0.3.0. When I run the install command without the version dotnet new --install Foundation.Api, it gives me a 401 unauthorized. Is there some kind of setting I need to add to my csproj? I'm 99% i've done this before without the version and it's ran just fine.

Here's the full error:
