Apple Configurator 2 & Anchor Certificates

Apple Configurator 2 & Anchor Certificates

When configuring the apple configurator with the MDM Server, I have typed in the Name and URL, but it says that it can't find server.  I seem to get "further" if I just type in the IP address and let it search for the server URL.  To be clear, I type in name of "MDM-Test" and hostname or URL of my ip address of server.  When I click Next, I see the following message as it searches:  Fetching trust anchor certificate from MDM Server.  It times out after a few seconds with "Unable to verify the server's enrollment URL.  The request timed out."

To give you a full picture, I am on a workgroup in my house.  I looked into the firewall concerns where I am "hosting" the MDM server and even disabled the firewall temporarily to see if it would fix the issue.

I have been unable to get this process to work and will take any advice you can give.
