Sometimes, older versions of clients like Xshell or XFTP may not support the latest security protocols or configurations used by newer AMI instances. The solution could be as simple as updating your XFTP or Xshell to the latest version. Additionally, ensure that the username is correct for the AMI type you're using and that the private key permissions are properly set. It's also important to verify the key format and ensure it's compatible with XFTP.

I'd advise you to follow this guidance to fix this problem: https://repost.aws/knowledge-center/ec2-linux-troubleshoot-sftp-connection

I'd also suggest that you read the doc regarding key registration on EC2 given the error message that you face.
