Hi,

But both method 1 and 2 not work at all. Could you please help to figure out?

Method 1: Enter user-data. After config completed, using SSH and server refused the public key Method 2: Use AWS Systems Manager. Unable to find runbook called AWSSupport-ResetAccess in Automation runbook

  • If you don't have constraints about turning off the instance, i would suggest that you create an image from the instance, and then create the instance from the image

You can find step-by-step instructions in the EC2 User Guide under the Troubleshooting topic "I've lost my private key. How can I connect to my Linux instance?". https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/TroubleshootingInstancesConnecting.html#replacing-lost-key-pair

Another method is to stop the instance; then mount the instance volume on another instance (you only have to run the second instance temporarily); replace the key file; then restart the first instance.

Here are some instructions - note that this is an external link; the content isn't produced by AWS: https://www.cloudtechtiq.com/blog/how-to-recover-key-file-aws-instance
