NGINX Deployment Woes

Hi;

I’m trying to deploy a relatively simple web page application that I’d like to run under nginx on ubuntu 22.04.3 LTS.  Like the previous poster who had problems with this, I think I’ve followed all the instructions…

• The application builds and runs fine in a local debug session.
• published the project as a self contained package for a linux environment.
• All files (from the publish folder) are in place and readable on the server.
• nginx config contains the proxy_pass statement pointing to the correct URL (In this case http://127.0.0.1:5000/)
• The web.config contains a valid server license.
• The application binary starts successfully :

jd@server:/var/www/html/application$ sudo ./application
info: Microsoft.Hosting.Lifetime[14]
Now listening on: http://localhost:5000
info: Microsoft.Hosting.Lifetime[0]
Application started. Press Ctrl+C to shut down.
info: Microsoft.Hosting.Lifetime[0]
Hosting environment: Production
info: Microsoft.Hosting.Lifetime[0]
Content root path: /var/www/html/application

• application : ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=31288f135a186eb28a16ea2f1ce476afa9df72f1, not stripped, too many notes (256)
• Response from server is:

and then a 404 on the subsequent call for wisej.wx

I’m obviously doing something a bit stupid (it doesn’t help that I seem to have acquired covid, and my brain is officially mush at the moment).

Can anyone offer some guidance?
