EC2 Instance Failing Status Checks and SSH Connection Issues

Question

I'm encountering an issue with my EC2 instance where only 1 out of 2 status checks have passed. Consequently, I am unable to connect to the server via SSH, and attempting to restart the instance has not resolved the problem. Could anyone provide advice on what further steps I can take to troubleshoot and resolve this issue? Any guidance would be greatly appreciated.
Thank you

Hello.

EC2 status checks include "System status check" and "Instance status check".  
If "System status check" fails, stopping and starting EC2 will change the physical host, so I think the problem will be fixed.  
In the case of "Instance status check", there are several causes, so it may not be fixed just by restarting EC2.

In the case of "Instance status check", if you check the system log etc. by following the steps in the document below, you may be able to check logs that will help identify the cause.
