Let’s say we have a .NET app running on an virtual machine. The app uses Github OAuth for authentication. Inside the virtual machine, the app runs on http://127.0.0.1:5000. The app should be available on https://example.com, so I have created an entry in nginx to send all requests towards https://example.com to http://127.0.0.1:5000: server { server\_name example.org www.example.org; listen 80; listen 443; location / { proxy\_pass https://127.0.0.1:5001/; } } So this works. My website can be reached from https://example.
