Just to rule out some possible confusion, immediately after getting started or powering up the system the sensors will be assumed closed. They will need to change status first. I do see sensor activity reported in Alarm.com history so the panel is reporting. Try closing those sensors and opening them again. Does the panel see them as open? If so, does Alarm.com then show their status?
A description of how sensors report sensor activity monitoring status in Alarm.com, along with applicable delays, is linked below:
Regarding Wifi, can you provide a screenshot or photo of the panel where you see that message? Your panel appears to be responding via broadband (wifi) only, actually. It is not responding to cell pings when I try them.
I would try a reboot. This is under Settings > Advanced Settings > Reboot Panel.
