I am trying to initiate an instance that is found here…
https://aws.amazon.com/amis/aws-tools
The instance is launched but when I try to login, I get the following message:
ssh -i oct9.pem root@ec2-50-16-125-42.compute-1.amazonaws.com
Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
If I launch a new instance using the built-in wizard, It works as expected with the same .pem key.
This AMI was working as expected till recently. I have used it before for a few instances. I would like to use this because it has several utilities pre-installed.
When you produce a new image from a running instance, you end up getting locked out of the running instance. I’m not sure why, but you can then re-launch a new instance from the image you just created.
It’s unclear whether or not this is the issue you’re running into, though.
