Hello @Jack_Stark, what version of android are you running? Also, do you have any luck if you enter the core’s IP into the app? You can do this by trying to select a different core and tapping on the “help” option.
Nuwriy,
Thanks for getting back. I am running two different Android versions on my Roon Remotes, and since neither was connecting i focused on the Roon Core Server. I know it is recommended to have the Core copper connected to the LAN, but there is no easy option for that in my case. I have been using a high end USB WiFi NIC successfully for some time, and then it began acting up. I managed to get it all to work by changing USB ports on the NIC even though it was in the USB3.0 port as recommended. It benchmarks better in one of the USB2.0 ports, and after that configuration change everything seems to be working fine now. It is unclear how the issue resolved unfortunately.
Jack
