Hi @Rick Angel ,
Welcome to Microsoft Q&A!
Please refer to: Signing in fails when using GCC High tenants.
Visual Studio Subscriptions subscriber portal and admin portal don't support GCC High tenants, also known as private or government domains. This limitation also applies to subscribers attempting to sign into the Visual Studio IDE. To access Visual Studio subscriptions, your organization needs to have a public tenant. For further assistance creating a public tenant, contact Azure support.
Sincerely,
Anna
