Error: Server refused our key or No supported authentication methods available

Posted on by Osama Mustafa in Cloud
If you use PuTTY to connect to your instance and get either of the following errors, Error: Server refused our key or Error: No supported authentication methods available, verify that you are connecting with the appropriate user name for your AMI. Enter the user name in the User name box in the PuTTY Configuration window.

The appropriate user names are as follows:

  • For an Amazon Linux AMI, the user name is ec2-user.
  • For a RHEL AMI, the user name is ec2-user or root.
  • For an Ubuntu AMI, the user name is ubuntu or root.
  • For a Centos AMI, the user name is centos.
  • For a Fedora AMI, the user name is ec2-user.
  • For SUSE, the user name is ec2-user or root.
  • Otherwise, if ec2-user and root don’t work, check with the AMI provider.

Thanks
Osama
