If the camera is powered up with a solid green LED (connected to the network) and Live View is functioning correctly, try turning off the recording rule(s) that is not working.
This can be done via the toggle switch under Video > Recording Rules in Alarm.com. Wait 5 minutes then turn the rule back on. Wait an additional 5 minutes and test.
If no resolution, delete the rule, wait 5 minutes, recreate the rule, wait 5 minutes, then test for resolution.
Do each rule one at a time.
When recreating rules, make sure you are following best practices for VA rules
