Hello, I see that you have activated an account, and I see successful uses of your login in Alarm.com history, but the login is failing because the panel has not yet communicated with Alarm.com.
In order to login and start using Alarm.com, the panel must have started communicating. It looks like a number of signals have been sent to it, but it has not yet responded.
You also would not be able to reset the password until the panel starts communicating, which is the reason for the odd message you are seeing I think.
It looks like you are using a Concord 4 panel, is that correct?
Take a look at the LTE Cellular Module and the L1 status LED on the cell board. Is that LED flashing? If so, how many times does it flash in a row before pausing and repeating?
