Register-PSRepository fails against authenticated endpoints
In PowerShellGet 1.0 you could add and use an authenticated endpoint. In 184.108.40.206 the Ping-Endpoint function gets a 401 against authenticated endpoints. This prevents internal authenticated repos from being added.
Thanks for identifying the issue. We’ll take a look at it.

Private feeds from MyGet can be used as they include url based authentication.
