Dear @alexdo, Thank you for your reply.

Hello, @venukommu

From what it seems like port 22 (ssh) is either closed or it’s not enabled for external access via the Firewall.

What you can do is to access your droplet using the console from your DigitalOcean control panel and check everything from there.

First you can make sure that sshd is running using the following command:

netstat -plunt | grep 22

If sshd is running then you can then make sure that ssh is allowed via the the firewall configuration tool.

You can make sure that UFW is running:

sudo ufw status

If it says it’s inactive you can enable it using this command:

sudo ufw enable

To allow all incoming SSH connections run this command:

sudo ufw allow ssh

An alternative syntax is to specify the port number of the SSH service:

sudo ufw allow 22

To allow incoming SSH connections from a specific IP address or subnet, specify the source.

sudo ufw allow from IPaddress to any port 22

Once this is done you can try to ssh again with the -vvv argument as it will show you a more verbose output.

Let me know how it goes.

Regards, Alex
