I am using an AWS ec2 instance. Previously I was connecting via Filezilla, Putty and MySQL using the provided key file with no problem. Now for some reason I am unable to access the sever.
Disconnected: No supported authentication methods available (server sent: publickey)
I have checked the public key is correct. I have checked the location of the ppk and pem files.
What else could be the cause of this error?
