Post API gives error on sending the request

Question

Hello,

I tried to post to API but the C# code give me error "Failed to connect to localhost/127.0.0.1:7091"

while if I tried to use Postman , it will work,

for the recieved Json in APIService

{\"FullName\":\"Mark\",\"About\":null,\"Email\":\"aaa@kkk.com\",\"Image\":null,\"Phone\":null,\"Password\":\"1111\",\"Addresss\":null,\"Birthdat\":null,\"Role\":null,\"Id\":null}"

for the APIService

public class ApiServices
    {
        public static async Task<bool> RegisterUser(string FullName, string Email, string Password,string Phone) 
        {
            try
            {
                var register = new User()
                {
                    Email = Email,
                    Password = Password,
                    FullName = FullName,
                    Phone = Phone,
                    Image = "",
                    About = "",
                    Addresss = "",
                    Birthdat = "",
                    Role = "2",
                    CreatedDate = DateTime.Now.ToString("yyyy-MM-dd")
                };
                var httpClient = new HttpClient();
                var json = JsonConvert.SerializeObject(register);
                var content = new StringContent(json,Encoding.UTF8, "application/json");
                
               
                var response = await httpClient.PostAsync("
                   https://localhost:7091/api/Woners/AddWoners", content);
                if (!response.IsSuccessStatusCode) return false;
                return true;
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message); // give error Failed to connect to localhost/127.0.0.1:7091"
                return false;
            }
        }

for the view model

private async void SignUpAsync()
        {

            var user = new User()
            {
                FullName=FullName, Phone=Phone, Email=Email,Password=Password
            };
         
             var responce=await ApiServices.RegisterUser(FullName, Email, Password,Phone);
              
}
                {
                    Console.WriteLine("fals");
                }
