For those who have trouble with the remote App on iOS/Android to connect to their Windows 10 we have a procedure to check to ensure your Windows 10 can see your App.
Thanks to @Zkeller who had this issue, you can follow those steps bellow:
Make sure you have version 3.5 or higher open on your PC.
Make sure that your Mac or PC and iPad/iPhone or Android device are connected to the same Wi-Fi (local network).
Check the firewall settings: In Settings > Update and Security > Windows Security > Firewall and Network Protection > Allow an application via a firewall, make sure that Audirvana is allowed to access the network.
Check your connection property: In Settings > Network & Internet > Check connection properties, make sure your Network profile is set to Private.
Restart your WiFi router because it may have a problem transmitting the connection used by Audirvana Remote (like the Apple Remote app that controls iTunes, which can be blocked for the same reasons).
