UWP App cannot resolve local domain from hosts file

I have a modified hosts file which is as follows:

192.168.10.10 library.test

and I try to connect to this domain from a UWP app using HttpClient like so

var client = new HttpClient();

var result = await client.GetAsync("http://library.test");
Console.WriteLine(result.StatusCode);

but this fails with the following exception

  HResult=0x80072EFD
  Message=An error occurred while sending the request.
  Source=System.Net.Http

Inner Exception 1:
COMException: The text associated with this error code could not be found.

A connection with the server could not be established

This same code works fine when using a host such as https://google.com

I did not reproduce your problem, when I try to modify the website library.test in the host and direct it to the local webpage, it can be accessed normally.

Please check the following:

1. Is 192.168.10.10 an accessible IP address? If you only access the local, you can change to 127.0.0.1.

2. If you do not set a port number, then the default is access to port 80, please ensure that there is accessible content under this port.
