Dokku DigitalOcean Deploy（无法访问Rails示例应用程序）

Question

Trying to deploy an app to DigitalOcean using Dokku

Followed the instructions on:
https://www.digitalocean.com/community/tutorials/how-to-use-the-digitalocean-dokku-application then:
http://dokku.viewdocs.io/dokku/deployment/application-deployment

Everything looked like it was deploying:

=====> Application deployed:
       http://178.62.95.224:35954

But then when we attempt to navigate to the app in a browser, we cannot access the app on http://178.62.95.224:35954/
( the IP address of the DigitalOcean VM and TCP Port assigned by Dokku )

What am I doing wrong ? Do I need to open the TCP port? ( in this case 35954 ) ( read that ports are open by default when ever a service listens on it... https://www.digitalocean.com/community/questions/opening-ports-on-my-server is this the case? )

Tried following the suggestion in: Rails Dokku deployments to Digitalocean receives random ports

echo "example.com" > /home/dokku/VHOST
dokku ps:rebuild ruby-rails-sample

and

dokku config:set ruby-rails-sample DOKKU_NGINX_PORT=80

but no luck!

You probably want to turn off ufw so that the random port is exposed to the world. You can get around this by instead using subdomains for virtualhosts.
