Question

I have a xamarin project working with azure sql database. It was working fine till today but I had to change my db and all server. From now whenever i want to open my connection app freeze and says is not responding. I tried to change my connection string but as I said it used to works fine. Here is my codes;
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="App1.MainPage">
<StackLayout>
<Button Text="Check Conn" Clicked="Button_Clicked"></Button>
</StackLayout>
</ContentPage>
MainPage.xaml.cs [sqlconn is proper its for an example]
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Data.SqlClient;
using Xamarin.Forms;
namespace App1
{
public partial class MainPage : ContentPage
{
SqlConnection sqlConnection;
public MainPage()
{
InitializeComponent();
string dbname = "dbname";
string srvrname = "servrnm";
string username = "username";
string password = "password";
string sqlconn = $"Data Source={srvrname}.database.windows.net;Initial Catalog={dbname};User ID={username};Password={password}" ;
sqlConnection = new SqlConnection(sqlconn);
}
private async void Button_Clicked(object sender, EventArgs e)
{
try
{
sqlConnection.Open();
await App.Current.MainPage.DisplayAlert("ALERT", "CONNECTION OPENED", "Ok");
sqlConnection.Close();
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
throw;
}
}
}
}
