This is either as a result of a faulty sync module, or something slightly different about your particular network environment. Some report, as you have here, that after a power outage, network outage, or internet outage, the sync module will not reconnect correctly, but many here will also tell you that after an outage, of any type, everything comes back up all on its own, once the services are restored, and I’m one of them.
I did extensive testing at home, before deploying one system at a very remote location, simulating many different types of system down, because I have potentially both unreliable power, and internet at this spot, and cannot readily attend to restart things manually. No matter what tests I performed, I could not stop it coming back up all on its own.
In practice, it turned out that my power was so limited I had to power off the entire system, including the router, during the dark winter months, every night, to preserve power, using a timer, probably for some 90 - 100 days in a row and it always came back up correctly, all on its own, in the morning.
If, after calling Blink support, they are able to come up with a good explanation as to why yours does not come back up, I’m sure we’d all be very interested to hear, so that we might better be able to assist others with the same problem, because as you see nobody really had any suggestions as to what might be the issue.
Hopefully it is something as simple as a faulty module, they agree to replace it, and you have no further ongoing issues.
