"Fail to add rule(s), cannot find the published port"

[slhck]

I run into this issue under Ubuntu 22.04 using the latest version of this script:

# ufw-docker install
# ufw-docker check

########## iptables -n -L DOCKER-USER ##########

Check done.

When I try exposing one container:

# ufw-docker allow traefik 80/tcp from anywhere
Fail to add rule(s), cannot find the published port 80/tcp of instance "traefik" or cannot update outdated rule(s).

However the instance is running and has its ports exposed:

# docker ps
CONTAINER ID   IMAGE                                                    COMMAND                  CREATED          STATUS          PORTS                                                                                                                 NAMES

What might cause this?

Hmm, it seems that when I remove the from anywhere part the rules get added:

# ufw-docker allow traefik
allow traefik 443/tcp traefik
ufw route allow proto tcp from any to 172.18.0.2 port 443 comment allow traefik 443/tcp traefik
Rule added
allow traefik 80/tcp traefik
ufw route allow proto tcp from any to 172.18.0.2 port 80 comment allow traefik 80/tcp traefik
Rule added
allow traefik 8080/tcp traefik
ufw route allow proto tcp from any to 172.18.0.2 port 8080 comment allow traefik 8080/tcp traefik
Rule added

The from anywhere used to work under Ubuntu 18.04.
