If you're having trouble connecting to your AWS EC2 instance via Putty software and receiving the error message "Server refuse key", there is a solution.
First, make sure you have the latest version of Putty (0.78) installed.
Then, create a keypair file with a .pem extension.
Use Puttygen to load this .pem file and save the private key. Be sure not to generate a new private key.
Finally, load this private key into Putty under the SSH -> Auth -> Credentials -> Private key file for authentication category.
- Now, AWS has made this process easy to generate the private keys. you can download the .ppk (private key) directly from the AWS portal while creating the key pair.
Following these steps should resolve the issue.
