[Solved] User IP Address returns Server IP from Web API Controller in ASP.Net

hello,

I have this method in web api controller

Then from client when i call this method form my default.aspx page instead of user ip its returning server ip

But when i call it from swagger it shows the user ip

[Route("api/ip")]
public IHttpActionResult getip()
{
    string ip = "Invalid";
    string ipAdd = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
    if (string.IsNullOrEmpty(ipAdd))
    {
        ip = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
    }
    else
    {
        ip = ipAdd;
    }
          
    return Ok(ip);
}

object input = new
{
    //incase if you want to pass search parameter to query
    //Name = txtName.Text.Trim(),
};

string inputJson = (new JavaScriptSerializer()).Serialize(input);
WebClient client = new WebClient();
client.Headers["Content-type"] = "application/json";
client.Encoding = Encoding.UTF8;
//URL + MethodName + Authorizationcode
//string json = client.UploadString(Website_Helper.APIURL + "/GetStudent/091fab0b-283c-42b8-b544-8d07cd0c8cbf", inputJson);
string json = client.UploadString(Website_Helper.APIURL + "/ip", inputJson);

I want a method in web api controller so i can get user ip and show on my default through api call from page behind

please advice
