Troubleshooting Dokku Not AccessibleFirst, make sure your application isn't giving any errors when it attempts to run:
dokku run <your-app> "<whatever is in your proc file>"
Get the :port number from the line with "upstream" in the following file: /home/dokku/<your-app>/nginx.conf
Try to "wget 127.0.0.1:<your-port>" from the host. Will it connect?
