Oh, I see. Thanks for replying Peter. However, I don't think that URL Rewrite is working fine for me because I get a DNS_fail error. I am sure that I have followed and installed ARR and URL Rewrite and included the inbound rule for my site. As you can see in the image below, I'm running my node express server on port 3030. How about the physical path? As far as I know, I should point it to the folder where it contains my app.js, node_modules, etc. right?
