I am trying to run a proxy with Nginx and I implemented the following tutorial as preparation. I did exactly as instructed here and I was served a 502 Bad Gateway result when I entered http://develop.microideation.local

I am on Ubuntu 18.04 and Nginx 1.14. I checked whether my firewall was blocking Nginx but it was deactivated even. Can anyone help me troubleshoot why I would get a 502 Bad Gateway given these configurations?
