Any ideas?

Local Hash Server Issue: exceptoin in calling external gRoot server

Hi @K2

I have spawned a local hash server successfully, and then executed the following (using the appropriate credentials)

Test-AllVirtualMemory -TargetHost 192.168.2.4 -aUserName 'user' -aPassWord 'pass' -MaxThreads 256 -ElevatePastAdmin -GUIObject

Test-AllVirtualMemory has the following configuration.
$gRoot = "https://pdb2json.azurewebsites.net/api/PageHash/x"
$HashServerUri = "http://192.168.2.100:3342/api/PageHash/x <-- where hash server is running

The result was the following (on the spawned hash server): <----Any ideas?

Should I replace Program.Settings.External with Program.Settings.Internal and also replace https://pdb2json.azurewebsites.net/api/PageHash/x with my local hash server?
