I’ve followed the instruction here: https://www.digitalocean.com/community/tutorials/how-to-install-nginx-on-debian-9 for setting up a webserver. However, after setting up the firewall through nfw and logging out, I can’t access the droplet both by ssh and the web console anymore. Fwiw, opening the web console gives me this repeatedly:
[UFW BLOCK] IN=eth0 OUT= MAC= ... SRC= ...
so it looks like the logging attempt has been blocked by ufw.
I’m pretty sure that when I ran ufw allow 'Nginx HTTP' and then ufw status the output didn’t contain OpenSSH. I should have noticed that :(
What should I do now?

Is this one maybe something support can help you with?
Otherwise, you may be looking at a full rebuild.
You probably want to use the “Recovery Console” which is a direct prompt (as if you were at the console on that computer with a keyboard and a monitor). Here you can log in your account, whether the firewall is blocking you or not via SSH. Apply the necessary fixes to your firewall (i.e. open port 22 early on) and try SSH again.
Note that DigitalOcean added a “Droplet Console” which is something else and that one may not be able to establish a connection.
