Cannot get data from node app via ISS reverse proxy

问题

In a windows server 2008 R2 Standard, I have a node 8 app that runs on localhost:3000.

In the same server , there is also a default website in ISS7 , in port 80, with the URL myproject.com

I managed to create a reverse proxy in that default ISS7 website, according to this tutorial. If I go to myproject.com, I get the node app

If I start searching, and basically doing a GET to myproject.com/laptops/names?name=hp&cat=offers, the status code is 200 OK , but I get back a json of empty results.

But I shouldn't get empty results, because the database is full of this category. In my laptop locally, in the same app, I get results. The node route for searching is not protected (no login, no token).

The node app also contains angular 6 for the front-end. The angular service does a get like this

return this.http.get('/laptops/names?name=' +name+ '&cat=' +cat, {headers:headers}) and the node route is set like router.get('/laptops/names',(req, res)=>{.....

I also tried the angular service like this return this.http.get('http://localhost:3000/laptops/names?name=' +name+ '&cat=' +cat, {headers:headers}) but I get just failed, with no code. At least having the URL in angular like so /laptops/names?name=.... gives a 200 OK status.

So how can I fix this and get results back? I dont know what causes this? The server? The proxy? Please advice.

Thanks
