iVCam sees Parallels, but times out attempting to connect to host

Has anyone tried using the iOS app iVCam by e2eSoft to connect to Windows 10 via Parallels Desktop 13 for Mac Pro edition? I have the latest build. I have the app set to pass through Windows Firewall. Set my router to allow UDP/TCP port 5898 to forward to MBP. The iPhone app can find the iVCam app in Parallels, but then times out trying to connect to Windows program (e2eSoft IVCam viewer app). I also tried typing the 2 IP addresses (listed in the Windows 10/Parallels drop down menu) directly into the iOS iVCam app, and then typing IP addresses with port {/5898} at the end of IP address entered. Any advice?

I contacted Parallels Cares on Twitter and was told, "Hi, please contact iVCam application support and check if it is compatible with a virtual machine or not." Tried to contact e2eSoft via their website, contact form page keeps erring out so I cannot. So... stuck.

Thanks for your time,
Todd
