After several days, SSH and SFTP no longer working. Connection closed by server.
I just got started with digital ocean and linux so I'm still learning the ropes. I set up a Ubuntu 14.04 x64 droplet a week ago and I was able to connect using ssh
user@ip via Cyberduck.
For some reason, I can't connect anymore although the login/password still works via Digital Ocean's console.
The response I get is "Connection closed by [server ip]"
