Cannot connect to Roon core?

SonicTransport and Ultra Rendu
ViaSat WiFi router


Sonic Transport to Rendu to USB DAC


Cannot connect to Roon Core. I am trying to run at different house with a different WiFi router and it will not connect to core. Tried Android phone, Samsung Tablet and Laptop, none will connect. It works fine at my other house with a NetGear router, but does not run at this house with a ViaSat router. I was able to get it to connect with my laptop if I disable the WindowsDefender Firewall. The ViaSat router works fine with all other devices and I am able to see the Sonic Transport and the Ultra Rendu over wifi, but when I launch Roon on my phone or tablet it does connect to Roon Core.

Hey @Scott_Leonard,

I am very sorry about replying this late :pleading_face: . I sure wish this wasn’t the case.

Are you still running into difficulties connecting your remotes to the Core? It might just be that the firewall is blocking the connection. Did you know that you don’t have to completely disable the firewall? You can add the Roonapp as an exception instead.

Please, let me know if we can help :pray:

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.
