Powered off my VPS, now can't SSH in

I powered off my droplet from the command line to do a snapshot. After powering back up I can’t ssh in. PuTTY gives me a “Server refused our key” error and prompts for password of the root user (providing the password doesn’t get me in either, it says “Access denied”). Any idea what’s happened?

I also found myself in a situation where I couldn’t log into a powered up droplet. I have no idea what I did for get in that situation since the droplet was working fine when I shut it down and took a snapshot.

I’ve made it a point to store two snapshots. Also when I take a snapshot, I restore the droplet from that snapshot. That way I know the snapshot is bootable. I suppose one snapshot is enough if you proved it was bootable.

@nathanscherneck No, not sure what has happened. Did you do update or major changes since last reboot? Go to the control panel, click the droplet, click Access-menu, click reset root password.
