Doorbell Pro offline and can't reconnect

Two or three days ago my Ring Doorbell Pro went offline. The Ring came with my new Lennar home which I closed on 13 months ago. The Ring has worked fine up until this point. Nothing has changed on my home network and my other Ring devices are all working fine still. I rebooted my router, no difference. I tried reconnecting the Ring to my wifi, no change. I did a Factory Reset on the Ring and still could not get the Ring to connect. The weird thing is that when trying to connect the Ring app tells me to look for the SSID Ring-344c4f but it never appears; however there is an SSID of Ring-344c4b with maximum signal strength (obviously connecting my iPhone to that network doesn't allowed the Ring to connect successfully). Any ideas? It's almost like my Doorbell Pro has changed its SSID, but surely that's not possible?
