On our EC2 instance (t2/Ubuntu) I've been able to ssh to the instance but can't any longer.
I installed Apache and then tried accessing the web server via the IP. With no luck I assumed possibly firewall issue so I then tried using the command
sudo ufw allow 'Apache'
and I believe I received "inactive", so I then entered the following
sudo ufw enable
After issuing the above and checking the ufw status I got
Output Status: active To Action From -- ------ ---- OpenSSH (v6) ALLOW Anywhere (v6) Apache (v6) ALLOW Anywhere (v6)
I then tried to ssh from the 2 accounts I had setup, but can no longer access the server via SSH.
Did I block SSH? If so how do I open this up again?
