Cannot install Windows Admin Center because of a CredSSP error

[BrainWaveCC]

I've tried to install several versions of WAC on my Windows 2019 server, and I continue to experience failure due to a CredSSP error.

This includes a full installation of WAC 2103, as shown in the attached.

Have you configured the Active Directory on the server?

Try sign out from your account and sign-in.

Check event viewer and see if you see any other valuable log files?

Just for test create another Administrator user and login and see if it works?

Try find a Windows 10 device and open the Feedback Hub app and select the Windows Server and submit a bug report and include all relevant log files from the Windows Server and also the PDF you just shared.
