I have an instance set up on AWS. It's an Ubuntu 12.04 server, and I can no longer log into ssh or sftp using my key.
I was logged into both ssh and sftp at the same time on a mac using terminal for ssh and cyberduck for sftp. I closed Cyberduck to go up for lunch and when I can back, I could no longer log in. I thought SFTP was the problem, but I closed the terminal also and could no longer log into the terminal.
When trying to log into ssh I get the following error:
Permission denied (publickey).
And when I try to log into SFTP, I get the following:
Login failed Login with username and password
I've made sure all of my login info is correct. Even if I didn't the info was bookmarked and working on cyberduck before it quit connecting.
The key has not changed nor has it changed places. I tried creating a new key, but got the same result. Nothing has change in the dashboard or on Amazon's side. The only thing I can think of that changed was I set the permissions of /var/www/ to 757 an then uploaded a large folder to it. Could that cause such a problem?
What are possibilities? Google hasn't offered me anything useful.
