Heya,

Just came across this answer and decided to write some general guidelines for anyone who comes across this in the future despite the old question.

It seems that you are having trouble running your second Node application on a single Dokku Droplet. Although the logs you’ve provided don’t indicate a distinct reason why this is happening, it’s possible that there might be a problem with how NGINX or Dokku is configured.

Here are a couple of things to check:

Port Binding: Ensure that your two node.js applications are set to listen on different ports. Unfortunately, two applications cannot listen on the same port at the same time, and this can stop an application from responding.
NGINX Configuration: Check that NGINX is properly configured to forward requests to your second Node app. Incorrect proxy settings could be the reason your second app is not responding.

Please refer to the DigitalOcean Dokku tutorial for further help:

Hope that this helps!
