Hello! We need some more information to help you.

  1. What type of instance are you using? Is it Lightsail?
  2. What is the CPU utilization in CloudWatch over the last few days until now?
  3. What security groups are you using? (The rules specifically)
  4. Have you checked the VPC flow logs?
  5. Do you have any health checks set up?
  6. Are you using a firewall service?
  7. Do you mean you cannot log into the instance via SSH or you can login to the WP control panel?

  • Thanks David for your response, 1. I am using EC2 instances 2. Its hovering around 50% which is unusual otherwise it remains very low 3. have created a custom security group with respective ports for 80/443/20 etc 4. No I did not ( I am not aware of) 5. Yes we have health checkup setup with alarm, all checks are passed 6. I am not sure, unless there is anything default 7. I can not log in from SSH and neither can connect to WP-ADMIn, basically the IP seems unreachable, though its an elastic IP and there is no change.

  • I would try restarting the instance. It's possible that it crashed on a software level and has not recovered. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-console.html
