Ad410 Device Mismatch just happened anyone else?

[Revo2Maxx]

So I have had my doorbell on the NVR for some time. Then it went offline I look at the area where it was and it says devices mis match? What? So I thought ok maybe Wifi issue, I test with SH app and I am able to connect so it is working on router ip no issue. So I then look and it is showing that it is right IP that is setup in camera and router. yet it don't want to load. So I remove from NVR and add back and it comes back online? Did something change in the camera. This is the first time I have seen this error from any cameras connected?
