Your Outline Server was installed correctly, but we are not able to connect to it

I'm trying to config Outline VPN and I bought a Droplet from Digitalocean with Ubuntu 22.

So, my server generated URI string correctly:

CONGRATULATIONS! Your Outline server is up and running.

To manage your Outline server, please copy the following line (including curly
brackets) into Step 2 of the Outline Manager interface:

{"apiUrl":"https://***.***.***.***:41591/nBGhsdKbtPJL35f8LfA","certSha256":"ABCSDED8BF654ABDD9FD46DB936D122FDDE7B4815SDDA2757B5133C1A74E7"}

in addition, script says:

Make sure to open the following ports on your firewall, router or cloud provider:
- Management port 41591, for TCP
- Access key port 28592, for TCP and UDP

This is my iptables -L result:

root@ubuntu-s-1gb-nyc1-01:/etc/init.d# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)

Chain DOCKER (0 references)

And ufw:

root@ubuntu-s-1gb-nyc1-01:/etc/init.d# ufw status
Status: inactive

As I have a digitalocean Droplet, this is my firewall config on digital ocean panel:

And finally, when I check my pot and IP, I give this result:

This is my outline manager report:

Does anyone know what is wrong with my configuration?
