NTM Won't Scan on Windows Server 2016 Standard

I am trying to run the NTM on Windows Server 2016 Standard but the scan gets hung on "Nodes Discover" and request made goes over 1600 and then starts from 0 again. The scan runs for 45 minutes to an hour and nothing comes up. I have this working fine on  a Windows 10 workstation but can't get it to discover devices on the Windows Server 2016 Server. I reached out to support but i am not getting any significant help from them. They don't have any engineers available to assist with troubleshooting at this point. Still waiting for their availability. Any ideas on how I can get it to scan on the Windows 2016 server?
