Everything was fine until maybe a week ago when all but main deco went offline in the app, but the network works just fine. Reinstalled the app, rebooted all the decos and the main router, no luck. Decos are in AP mode, they have reserved ip adreses in the router dhcp (why no fixed ip setting in the app?!) and they all work fine and respond to ping, only the app says they are offline.

They are v2.0 EU all on latest firmware, 1 main deco and 4 satelites, 1 sat is via lan, 1 sat is via powerline, and last 2 are via wifi mesh
