  I have an instance on AWS free tier `t3.micro`.
  
  The problem I faced is suddenly my instance was not able to connect with other instances.
  
  I have checked on the dashboard and see that on the status check column it was showing `1/2` checks passed while another instance is `2/2` passed
  
  On the Alarm status column, it was showing `1/2` in alarm.
  
  I check on alarm details and it was showing a green tick on CPU utilization while the red triangle icon is showing on status check failed.
  
  I also check the monitoring of the instance and found that the status checks failed graph has 1 count.
  
  I have restarted the machine and now it is `2/2` passed.
  
  What are the reasons AWS EC2 status check fails?
