Unable to connect to Ubuntu after reboot

Question

Dear All,

I restarted the Ubuntu machine. I use Elastic IP to access the machine.

The machine reboots well - however I am unable to access via ssh like I used to before.

one of the checks is failing - 
System status checks
 System reachability check passed
Instance status checks
 Initializing

Any advise what may have gone wrong post Ubuntu restart?

TIA
