Issue: : MagicEndPoint - IIS server fails to launch IdP page 'HTTP Error 500.30 -  http://ASP.NET  Core app failed to start'

Symptoms:

  1. IdP server is working fine.
  2. Update Windows on the server - including any KB updates for the .NET Framework.

3. Reboot the server
4. Launch the IdP web page

Expected result: The launch of the IdP page should be successful.

Actual result: Instead, the IdP page failed to launch with 'HTTP Error 500.30 - ASP.NET | Open-source web framework for .NET Core app failed to start'

 


By reviewing the Event Log we can see that SQL starts after IIS:
 


Work-around:
5. Change the IIS service to 'Automatic (Delayed Start)
 


6. Reboot the server that is hosting IIS

>> At this point the IdP Page will be launched and displayed successfully.
