I followed the instructions below using ufw, it worked fine and tested instantly for ports 80 and 22, but for 443 I get Connection refused on the test, and no ufw block or in syslog or sign of attempt in auth.log.
Does DO block 443 on their own?
$ sudo ufw status | grep 443
To Action From
443/tcp ALLOW Anywhere 443/tcp (v6) ALLOW Anywhere (v6)
