Hello, @lilboat

Can you please make sure that the droplet is online and that the ssh port is open or your IP address whitelisted?

Do you have UFW enabled on your droplet? You can check this using the following command:

sudo ufw status

If UFW is disabled, which it is by default, you’ll see something like this:

Output
Status: inactive

To enable UFW, use this command:

sudo ufw enable

To configure your server to allow incoming SSH connections, you can use this command:

sudo ufw allow ssh

Let me know how it goes.

Regards,
Alex

      Hello, @lilboat

      Could you please share the output of these two commands:

      sudo ufw status

      and

      sudo netstat -plunt | grep ssh

      You can also try to enable Keep-Alive in PuTTY or try to connect using different ssh client.

      Regards,
      Alex
