How do I deploy a Node.js HTTP/2 application onto Google Compute Engine using a Docker image?

This used to work until a week ago, when the VM ran out of memory due to a missing finally in a try-catch. So, I tried to re-deploy with this fix to a new instance and now nothing is working.

Here is the git repository of the server:

I use the GCP console shell to build and push the image. It is on the VM with the container available and running. However, when I try to connect to the external IP address, nothing is there.

Here is a screenshot of the docker ps & docker images:

Halp!!!! lol
