From the error message we have that the attempt is performed against IP address 22.25.236.130 which does not seem to be associated to any of the Auth0 public cloud regions (US, EU and AU).

You should confirm that the machine from where that call is being performed is either not behind a proxy or if behind a proxy that the proxy works correctly when invoked from .NET.
