Tried setting permissions on the intepub/wwwroot folder to {machinename}\IIS_IUSRS (Read, Execute)

  • that didn't solve the problem

Reviewed the IIS installed components - add Basic Authentication

  • that didn't solve the problem

Solution found here:
Service not accessible when "Enable 32-Bit Applications" set to true
HTTP Error 500.19 on Internet Information Services (IIS) webpages - Internet Information Services

I modified this file as described but that didn't resolve the problem
C:\Windows\System32\inetsrv\Config\applicationHost.config

Finally ran this command and then it started working

C:\Windows\system32\inetsrv\appcmd.exe set config -section:system.webServer/httpCompression /-[name='xpress']

The result was:

This finally resolved the problem!
