Kubernetes NGINX Ingress Controller 404 Not found / Object not found - nginx

Question

I am taking a course in Udemy and I am new to the world of Kubernetes and I am trying to configure ingress nginx controller in Kubernetes but it returns 404 not found when i send a request at specified URL, it has been 10 days that I am trying to fix it, i've looked at similar questions but none of their answers are working for me. I am also using Skaffold to do build/deploy image on docker hub automatically when i change something in files.
My express app server:
app.get('/api/users/currentuser', (req, res) => {
res.send('Hi there');
});
app.listen(3000, () => {
console.log('[Auth] - Listening on port 3000');
});

I also executed command from NGINX Ingress Controller docs:
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.0.5/deploy/static/provider/cloud/deploy.yaml
I also changed hosts.file in the system:

Could there be a problem with the Windows IIS web server? since I previously configured something for another project, and in the screenshot above I see:
Requested URL http://ticketing.com:80/api/users/currentuser
Physical Path C:\inetpub\wwwroot\api\users\currentuser
Also the screenshot shows the port :80 at the requested URL but I have the server port 3000? + when i request at https it returns:
502 Bad Gateway
nginx
also C:\inetpub\wwwroot is strange to me.
Any ideas would help me a lot with continuing the course.

Answer 1

After a few days of research I finally solved the problem, the problem was with IIS Web Server which I had enabled when I was working on a project in ASP.NET core, I uninstalled it and the problem was solved.
How to uninstall IIS from Windows 10:
Go to Control Panel > Programs and Features
Click Turn Windows features on or off
Scroll down to Internet Information Services
Click on the square next to Internet Information Services so it becomes empty
Click OK and restart the PC (required).
