                HttpResponseMessage response1 = await ServiceCall<LoginModel>.postData(URLPREFIX + "/authenticate",loginModel);
                if (response1.IsSuccessStatusCode)
                {
                    loginFlag = await response1.Content.ReadAsAsync<bool>();
                }

                if (loginFlag)
                {
                    return RedirectToAction("Index","Home");
                }
                else
                {

If you are using Json as a parameter to your controllers, use [formbody] in your web API. It should work. Let me know if it doesn't work.

You must add [ApiController] in controller level. code is following

[ApiController]
[Route("[controller]")]
public class LoginController : ControllerBase 
{
    const string URLPREFIX = "api/account";
    
    [HttpPost]
    public async Task<IActionResult> Login(LoginModel loginModel)
    {
        var loginFlag = false;
        HttpResponseMessage response1 = await ServiceCall<LoginModel>.postData(URLPREFIX + "/authenticate",loginModel);
        if (response1.IsSuccessStatusCode)
        {
            loginFlag = await response1.Content.ReadAsAsync<bool>();
        }

        if (loginFlag)
        {
            return RedirectToAction("Index","Home");
        }
        else
        {
            return View();
        }
    }
}
