Connecting 2015 Playbar

I have a 2015 legacy system that was stored for 10 years while I travelled overseas for work. I have subsequently returned and tried to set up my Playbar, I have anew network as you would expect. The Playbar has been factory reset and connected to the power and router, the router is connected via cat6 Ethernet cable. I can see the unit on my network however not on my phone or via the S1 or S2 app. Any suggestions how I can resolve this as I have a number of Play 1 and Sub to connect too. I already have a Move (1) connected
