I am attempting to configure Nginx to run my flask/python application on a Linux Centos 7 server. I am getting a Bad Gateway 502 error. I am new to using Nginx so I am hoping I am going the right direction. Here are my files. Error message [error] 91680#0: *23 connect() to unix:/var/www/MyApp/MyApp.sock failed (111: Connection refused) while connecting to upstream, client: 204.235.114.162, server: _, request: “GET /favicon.ico HTTP/1.1”, upstream: “uwsgi://unix:/var/www/MyApp/MyApp.sock:”, host: “00.106.228.85”, referrer: “http://ip.address/MyApp/run.py”

This error means that nginx is unable to connect to uWSGI through the socket. This can happen in one of two cases:
Your config files looks fine, so I’m guessing it’s 1. Is uWSGI running? You can check by running this command and seeing if it outputs anything:
sudo ps wwaux | grep -i uwsgi
