Device disappeared, RPI, V 3.512

I have 2 systems in the house, both on RPI, All going well for some time now. Suddenly one of the devices is missing when i open Volumio. They are called Volumio-O, which is upstairs) and Volumio-Office, which downstairs). Both Ethernet connect. Volumio-O is gone. Volumio-O.local doesn’t work either. This is true whether I use Windows 10, or Android to connect to Volumio. I have re-booted everything, tthe RPI, swapped cables, all my connection points can see the Volumio-office but not Volumio-O system. Any ideas? Thank you.

You could try to reach it via myvolumio.org

On your phone, disable wifi (so you’re outside the network where your Volumio systems are). Go to

[Volumio - The Music Player]

See if you can find and connect to the misbehaving Volumio by clicking on the green arrow, if it’s there. You can then check its network settings.

Thank you. It’s listed on MyVolumio, and enabled, but no green arrow.

Can you connect it via ethernet and then check the network settings.
