Android app can't find my device (Raspberry Pi, TP-Link Deco P9)

Hey all,

I run Volumio (version 4.071) on a Raspberry Pi 3, which is connected via ethernet cable to my router. Volumio plays music just fine, but the Volumio app on Android can’t find my device.

I suspect that the problem is connected to my WiFi Mesh system, it’s a TP-Link Deco P9. By reading some posts in this forum I got the notion that both the WiFi connection on my phone and the Mesh system must use the same subnet mask. I didn’t really understand the details …

When I log into my Mesh system’s configuration, I get this status information:

Internet

Status: Online
Internet Connection Type: Dynamic IP
IP Address: 192.168.0.38
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
Primary DNS: 192.168.0.1
Secondary DNS: 0.0.0.0

LAN

MAC Address: 00-5F-67-21-B0-F8
IP Address: 192.168.68.1
Subnet Mask: 255.255.255.0

Is that helpful? I would appreciate your advice.
