How to pass "ajax error 500" with Windows Admin Center 24.10 (v2)

Hi there,

I did successfully deploy the new v2 of Windows Admin Center (Build 2.4.2.1, 2410). I've got a Dell HW as a server, where I have Windows Server Core 2019 running. The server core runs as a Hyper-V host. It has been nice and easy to run Hyper-V with Windows Admin Center so far but the most recent v2 seems to be causing all kinds of head-ache. Seemingly everything worked.

• WAC install can be run from admin cmd as is
  • Setup TCP port as 44301 -> ok
  • Check firewall -> ok
  • ensuring that my star-certificate can be used -> ok
  • set trusted hosts as all -> ok
  • set anonymous use as ok ->
  • set windows authentication as the method -> ok
  • setting my own FQDN as de-facto connect point -> ok
  • it even checks that PS remoting is on -> ok
• I tested via powershell that my firewall works
• starting WindowsAdminCenter service
• running from a client pc the https://FQDN:44301
  • Great, it works, loads bootstrap and everything
  • I get in with my admin (<local machine>\Administrator)
• Now here is where it gets funny
• I try to click to my "Server" -> "ajax error 500"
  • this is so weird, no real error stack
  • kind of getting a feeling that the WAC v2 is just incomplete
  • How do you get pass this point?

(above the screen cap on the error after clicking my Server "Hyperpilvi" -> "Connection error")

Any ideas how to resolve this one?
