My ssh keys were all right till I installed let’s encrypt. since then I had this error 

port 22: Connection timed out

I’ve tried to reset my password and tried to install my ssh keys by hand and not from the terminal, nothing works! I can’t access my root user neither my deploy user. How can I fix that, please?

try creating a new user with sudo privileges - install your key(s) to that user and attempt a login

  • adduser SOMENAME

  • usermod -aG sudo SOMENAME

  • vi /home/SOMENAME/.ssh/id_rsa.pub paste your public key

  • cp -v /home/SOMENAME/.ssh/id_rsa /home/SOMENAME/.ssh/authorized_keys

  • chmod 600 /home/SOMENAME/.ssh/authorized_keys

Replace SOMENAME with a name of your choice.

Ensure your KeyAgent is running on your working computer

  • eval `ssh-agent`

  • ssh-add ~/.ssh/id_rsa

I am assuming your key name is id_rsa and that you are working on a linux of macOS system

then try and ssh to your droplet with the new user using the IP of your droplet

  • ssh SOMENAME@XXX.XXX.XXX.XXX

Can you access it via the DigitalOcean terminal?
