SSH Error: Connection refused after 'sudo reboot'

I am running a MySQL server on Ubuntu 14.04 LTS (vmlinuz-3.13.0-52-generic). I had run the following via SSH, and, after a reboot of the Droplet, I can no longer connect via SSH:

sudo apt-get update sudo apt-get upgrade Saw a message about restart required sudo reboot

When I SSH:

~ $ ssh xxxxxxxxx@###.###.###.### ssh: connect to host ###.###.###.### port 22: Connection refused

My /etc/ssh/sshd_config file is set to receive connections on port 22, I have not changed this.

Steps I’ve taken:

I tried to power cycle my Droplet via the Digitalocean control panel and am still receiving the same error when I attempt to SSH into my Droplet.

I have attempted to gain console access via the Digitalocean control panel, but I am not receiving a command prompt, only the following (it just sits there):

Ubuntu 14.04.2 LTS hostname tty1 hostname login: Cloud-init v. 0.7.5 running ‘modules:final’ at Thu 09 Jul 2015 18:09:29 +0000. Up 5.85 seconds Cloud-init v. 0.7.5 finished at Thu 09 Jul 2015 18:09:29 +0000. Datasource DataSourceDigitalOcean. Up 5.93 seconds

Any ideas?
