UFW does not block any ports (Ubuntu 22.04) [migrated]

UFW does not block any ports (Ubuntu 22.04) [migrated]

On my fresh Hetzner Cloud server, the ufw seems to be ineffective. The status output is the following:

Status: active

To                         Action      From

443                        ALLOW       Anywhere
OpenSSH (v6)               ALLOW       Anywhere (v6)
80 (v6)                    ALLOW       Anywhere (v6)
443 (v6)                   ALLOW       Anywhere (v6)

Despite ufw being active on this fresh install, all ports are accessible (I removed the IP from the screenshot):

Is a reboot required after activating ufw or an ufw rule?
