# What are the reasons AWS EC2 status check fails?

(Asked by: username_0 on 2022-01-24)

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?
