Server is inaccessible. I tried recreating instance, resetting key pairs, and nothing works. Please help!

Question

I've attempted to SSH into my instance with putty, and I always get this message.
---------------------------
PuTTY Fatal Error
---------------------------
No supported authentication methods available (server sent: publickey,gssapi-keyex,gssapi-with-mic)
---------------------------
OK   
---------------------------

I tried creating new instances and still can't get in. I tried creating new keys, set the security settings and still nothing.

It's been 4 days and all of my websites are now down. :(

I had to verify my credit card (which I've never had to do before, so that was strange). After verifying it, the problem persisted. I can't even view the public sites. I tried restarting the instance as well. Still no avail.

Please help me.

Answer

Hi,

Did you try connecting to EC2 instance through EC2 instance connect from AWS console itself. [EC2 Instance Connect Methods](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide//ec2-instance-connect-methods.html)

Click on your instance's instance id on EC2 console -> Connect to instance -> EC2 Instance Connect -> Enter User Name(if custom) -> Click Connect

You should be able to get in to your instance from here and get your website up and running first.
