WAC fails to open on brand new Windows 11 machine

Good morning,

I recently got a new workstation for my department, and it came with Windows 11 Pro.  I tried installing Windows Admin Center 2110 (tried 1910.2 first with the same result) as I use it quite a lot and it fails to open.  I simply get the following error:

 

This page isn’t working right now

localhost can't currently handle this request.
HTTP ERROR 500

 

Nothing of any real use in troubleshooting.  I have uninstalled and re-installed a couple times, the last time changing the port number to 6517 in case there was a conflict or something.  I tried with and without Firewall also to no avail. I am hoping someone has come across this before and is able to help me out.

Error 500

    After installing and starting it for the first time, it did prompt you to select the certificate for your user? Opening in browser or using the system tray icon of Windows Admin Center (Right-Click, open) gives you the same result? netstat -an | find /i "6517" does show you a Listening port?

      No prompt for the certificate.  Went strait to the error...

      Happens no matter the method of opening, by way of the application or a web page direct request.

      I will try the netstat in the meantime.
