Description Of Issue

I cannot connect via WiFi to the Roon Endpoint hosted on Sonic Transport with my Android phone or my LapTop or my Samsung Tablet. I get the following message on my phone when I try and connect: sonicTransport Linux 5.6.13-100.sgc.fc30.x86_64/ Version 1.8 (build 778) stable.
I can communicate with the Sonic Transport and Rendu via my LapTop over Wifi (reboot, power down, see music library, etc), but I just cannot connect my Roon Control App to Endpoint via WiFi. When I connect my LapTop to Sonic Transport via hardline ethernet it works fine, connects with no problems and all Roon functionality works great. It seems like a FireWall issue with the ViaSat router, but I talked to ViaSat tech support and they said the issue is not on their side (of course).
At my other home (main home) with the exact same setup, with the exception of the ViaSat router (NetGear Nighthawk router instead with Simply Bits ISP) everything works fine.
