404 Error when deploying Node/Express/Angular to Digital Ocean server

I have a Node/Express/Angular project I created that runs great on my local system.

The Grunt build produces a "server" dist file that I can run locally using "localhost:3000". But when I upload the site to my Digital Ocean server instance, I get the following 404 when I run it and try to access it via the IP address and port.

I'm not sure why it would work on my localhost and port number and not with the IP on the server and port number.

Any ideas??
