Cant hit localhost

[DayneD89]

For some reason, I am unable to hit a localhost address. To replicate this I am hosting http://jsonplaceholder.typicode.com/ locally on port 3000 and I can confirm that accessing this url through a web browser brings up the same information as using the site. For this example I'll be using the path /todos/1/.

int type = 2;
string uhost = (type == 1) 
    ? "https://jsonplaceholder.typicode.com"
     : "http://localhost";

new RestAssured()
    .Given()
        .Name("Localhost Test")
        .Port((type == 1) ? 80 : 3000)
    .When()
        .Get(uhost+"/todos/1")
    .Then()
        .TestStatus("test a", x => x == 200)
        .Assert("test a")
    .WriteAssertions();

When type is 1 this runs as expected, however, when I change it to 2 (localhost) it gets back a HTML page and a 404 (Thus it fails to parse as Content-Type is html, but I set a custom parser to just print the _content to the console for this content-type).

Localhost does work if I change this to;

new RestAssured()
    .Given()
        .Name("Localhost Test")
        .Port((type == 1) ? 80 : 3000)
        .Host(uhost)
    .When() 
        .Get("/todos/1")
    .Then()
        .TestStatus("test a", x => x == 200)
        .Assert("test a")
    .WriteAssertions();```

However, needing a workaround isn't elegant.
