UFW blocks port 8443 when I explicitly allow it

For whatever reason, whenever I turn on ufw, it blocks access to port 8443/tcp even though I have it explicitly allowed. For example:

[root:test:~/test]# ufw status numbered

Status: active



     To                         Action      From

     --                         ------      ----

[ 1] 8443                       ALLOW IN    Anywhere

[ 2] 8443 (v6)                  ALLOW IN    Anywhere (v6)

Based on this rule, I should be able to access to port 8443/tcp. I'm listening on 8443/tcp on SSH:

[root:test:~/test]# netstat -antp | grep -i listen

tcp        0      0 127.0.0.1:27017         0.0.0.0:*               LISTEN      763/mongod

tcp        0      0 127.0.0.53:53           0.0.0.0:*               LISTEN      19880/systemd-resol

tcp        0      0 0.0.0.0:8443            0.0.0.0:*               LISTEN      2456/sshd

tcp6       0      0 :::80                   :::*                    LISTEN      1276/docker-proxy

tcp6       0      0 :::8443                 :::*                    LISTEN      2456/sshd

So with this being said, every time I enable ufw, my SSH connection drops. The only way I can get back on it is by accessing the UI console from within Digital Ocean and disabling ufw.

Any idea why this could be happening? This is extremely mind puzzling.

firewall ufw
