Hello,

I installed the firewall but now I can not access with SSH. Please what should I do?

I followed this guide:

Thank you.

Before enabling the firewall, did you open a port in order to access the server using SSH? Normally this would be port 22. You can open it with:

sudo ufw allow ssh

But if you’ve changed your ssh port to something else, you’ll need to specify it explicitly. For instance, if you’ve changed it to 2222:

sudo ufw allow 2222/tcp

You should be able to access your droplet via the web console in order to add new rules.
