I checked the connection after creating the instance, But it seems that at some point something went wrong with the instance.
After restarting the instance, It works fine, but I don't know the cause of the problem.
[Problems]
- Cannot connect using PuTTY
- 'ping' to Elastic IP is not responding
- The state of the instance is RUNNING, but failed to check the status of the instance
[Installed on EC2]
- Docker
- Apache + PHP (Container)
- MySQL (Container)
The CPU usage increased on 04/30/2022 03:00, and the instance status check fails after that.
And there was no traffic at this time.
I checked the logs, no errors are found.
What more should I check?
