I did factory reset it this weekend
The garage cam shows an ADC install date in February, so it would not be able to communicate at all unless it is deleted and relearned into ADC.
The first step to start troubleshooting would be to go to the video page in Alarm.com and go to settings > video device info and delete that garage camera.
Reconnect the camera to your wifi. This is also necessary if factory reset. You can use WPS or AP mode. Instructions are in the link below:
Then try adding the camera, make sure your device is on the same local network as the camera.
