can't log in via ssh all of a sudden (was working before)
I set up an SSH key for my droplet 9 months ago when I started it, and have been logging in to my server from terminal using the root user with no problem. But today it suddenly stopped working. When I typed in the command:
It says "Permission denied (publickey)".
I don't know what went wrong. I don't remember changing anything. But it just suddenly stopped working. Any ideas what the problem could be?
