The proxy tunnel request to proxy failed with status code '407'

[solarding]

Using a very restricted Laptop, behind Proxy (no way to change the winhttp proxy )
I got this error, there is no way for interactive authenticate

PS C:\Users\abc\source\xRM_API\xRM> dotnet nuget push --skip-duplicate --interactive --source https://pkgs.dev.azure.com/xxxx/_packaging/xRM/nuget/v3/index.json --api-key AZ xxxx.nupkg

The http client should be sending the default credentials on the above logged call - does the proxy require alternate credentials than default?

Additionally, is this a windows machine? Can you provide more information on the OS being used?
