Issue with Ports deploying to Dokku Droplet

Hi There

I am a really novice using dokku and follow this tutorial : https://auth0.com/blog/hosting-applications-using-digitalocean-and-dokku/

But even the basic steps did not work to reach my simple HELLO WORLD application

I have this status :

dokku proxy:ports dokkuexp -----> Port mappings for dokkuexp -----> scheme host port container port http 58270 5000

But trying to reach my app in both ways give me a The site can’t be reached :

http://MYdropletip:5000 or http://goodfy-dokku-at-docean:5000 and even

http://goodfy-dokku-at-docean:58270

I have checked instructions regarding uff … but even with status root@goodfy-dokku-at-docean:~# sudo ufw status Status: active

To Action From

22/tcp ALLOW Anywhere 80/tcp ALLOW Anywhere 443/tcp ALLOW Anywhere 2375/tcp ALLOW Anywhere 2376/tcp ALLOW Anywhere 5000/tcp ALLOW Anywhere 22/tcp (v6) ALLOW Anywhere (v6) 80/tcp (v6) ALLOW Anywhere (v6) 443/tcp (v6) ALLOW Anywhere (v6) 2375/tcp (v6) ALLOW Anywhere (v6) 2376/tcp (v6) ALLOW Anywhere (v6) 5000/tcp (v6) ALLOW Anywhere (v6)

Things do not work … What do I missing ? Thanks in advance
