2-3 weeks my normal schedule for 2 instances of Canvas started at different times.
Additionally I noted that my Stream Deck was unable to control the Canvases.
Alexa and the App where able to control the Canvases.
DHCP server (opnSense box) showed status as off-line, they're in the same VLAN as ALL my other IoT devices (62) which work flawlessly.
With 1 unit I tried a soft reset, I could pair via the app, but no change from above.
Tried hard reset.
After 3 days and MANY hours I have been able to pair the Canvas and Andriod App.
@"Josh N." I had a similar issue.
It boils down to the fact, that the Nanoleaf Canvas updated to FW 6.2.1 automatically and without myself even been asked for.
During that update Nanoleaf changed its MAC address itself. That triggered that the router assigned a new IP Adress (and not using the fixed assigned one).
I was similar puzzled that my setup did not work from one day to another.
It took me a while figuring out that a FW update caused all this; plus it brought additional bugs in on top, e.g. that ssdp does not provide an IP Adress.
