Tweak Nginx configuration which is taking 60 seconds to load a vanilla Angular app

I need some Nginx expert here. On Windows 10, I'm using Nginx to reverse proxy a vanilla Angular app. The reverse proxy is working but for some reason is taking 60 seconds to load. I don't know why exactly 60 seconds. I think there is some specific configuration I need to set on the configuration files. You can download the involved files from this repository: [login to view URL] For more details about the problem, please, go here: [login to view URL] I require that the Nginx reverse proxy works with: $ ng serve I require the proper tweak to be done before: 2018-07-26 16:00 UTC I think it is one or two lines configuration. Thanks!
