WebAPI controller not working while another one does

I have an API that works fine locally and when I move it to the live environment it doesn't.

The main POST action on the affected controller returns:

NotFound

With a test GET action I get back:

"Message": "No HTTP resource was found that matches the request URI

Strangely, when I uploaded a testController with the same test action as used in the main controller I get a proper response from the API.

This is the test that works fine:

public class TestController : ApiController
{

    [AllowAnonymous]
    [HttpGet]
    public HttpResponseMessage helloWorld()
    {
        return Request.CreateResponse(HttpStatusCode.OK, "HelloWorld!");
    }
}

The controller which does not work:

public class DeviceController : ApiController
{

    [AllowAnonymous]
    [HttpGet]
    public HttpResponseMessage helloWorld() // This returns: "No HTTP resource was found that matches the request URI 'http://api.mySite.com/api/Device/helloWorld'."
    {
        return Request.CreateResponse(HttpStatusCode.OK, "HelloWorld!");
    }

    [AllowAnonymous]
    [HttpPost]
    public HttpResponseMessage Login([FromBody] LoginObject loginObject) // This returns: "NotFound"
    {
        ...
    }

}

Here is the web config:

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(

            name: "API Default",
            routeTemplate: "api/{controller}/{action}/{id}",
            defaults: new { id = RouteParameter.Optional }

        );
    }
}

I spent some time looking for the answer to this problem in .NET 7.0 after I had made a new project (which automatically created a WeatherForecastController).

It turns out that the project had also automatically created a file named proxy.conf.js. In the file, the context: setting was set to "/weatherforecast". I changed it to "/api" instead and then changed [Route("[controller]")] to [Route("api/[controller]")] in both controller files. The controllers worked fine after that.

For poor sap's like myself in the future: Ensure the methods on your controller are public.

Try to add explicitly declare of route like by acrion

[Route("api/Device/helloWorld")]
[AllowAnonymous]
[HttpGet]
public HttpResponseMessage helloWorld()

or

[RoutePrefix("api/Device")]
public class DeviceController : ApiController

and then

[Route("helloWorld")]
[AllowAnonymous]
[HttpGet]
public HttpResponseMessage helloWorld()
