Error : No supported authentication methods available on AWS

Question

SSH for my AWS server is not working for Filezilla and Putty. Error: Disconnected : No supported authentication methods available The error is similar like setting up AWS SSH for the first time Incorrect .ppk file Wrong username Wrong IP Are there any other possibilities? The solution is that all the above problems should have permissions. Here's an example: /folder/ec2-user/ - 700 /folder/ec2-user/ .ssh/ - 0600 /folder/ec2-user/ .ssh/authorized_keys - Select the correct answer from above options

Answer 1

This error can occur immediately after changing the user’s home directory by: Command: sudo usermod -d var/www/html username For e.g: I have recreated the instances to use Amazon Linux instead of Ubuntu. Now, I have to switch to use "EC2- user" as the username instead of "Unbuntu" to make sure that any error is not occurring. It can also occur due to lack of permission to the authorized_key file in ~/.ssh The permission of this file should be 0600 and permission of ~/.ssh should be 700.
