Any of those help So the issue was as Punit Ganshani MVP asked. The firewall at our server house only allowed http and once https was added to the list the site worked instantly.
for the suggestion. This was my first asp.net project so i just assumed that I messed something up in the code or the project itself.

help you fix your problem Create a database with the names and paths of the downloaded images. Upon onCreate() (or wherever you want to do the check), read the database and check if it's empty or not. If not, then use the images.

it fixes the issue I'm going to go with Martijn B's answer. There's a DNS issue on the internal network. Somewhere on of the DNS servers is a definition that maps http://companywebsite to an ip address like 192.168.1.20 or whatever.
I would open a command prompt on your PC and type
code :
ping new_website_name.com

Does that help I use this little function to detect Public Wifi redirects to sign on page. If this function returns false, it means you could not connect to the intended page despite having your 3G or Wifi on. With this you can show the user any page, for example a "No Internet Connection" page.
code :
public boolean networkSignOn() {
    HttpURLConnection urlConnection = null;
    try {
        URL url = new URL("http://clients3.google.com/generate_204");
        urlConnection = (HttpURLConnection) url.openConnection();
        urlConnection.setInstanceFollowRedirects(false);
        urlConnection.setConnectTimeout(10000);
        urlConnection.setReadTimeout(10000);
        urlConnection.setUseCaches(false);
        urlConnection.getInputStream();
        return urlConnection.getResponseCode() == 204;
    } catch (IOException e) {
        Log.v("Walled garden check - probably not a portal: exception " + e, "");
        return false;
    } finally {
        if (urlConnection != null) urlConnection.disconnect();
    }
}

Hope this helps Solution:
You can use DependencyServiceto implement it .Refer the following code.
code :
using System;
namespace app1
{
  public interface INetworkAvailable
  {

    bool IsNetworkAvailable();
  }
}
using System;
using Xamarin.Forms;
using Foundation;

[assembly: Dependency(typeof(IsNetworkAvailableImplement))]
namespace xxx.iOS
{
  public class IsNetworkAvailableImplement:INetworkAvailable
  {
    public IsNetworkAvailableImplement()
    {
    }

    bool INetworkAvailable.IsNetworkAvailable()
    {
        NSString urlString = new NSString("http://captive.apple.com");

        NSUrl url = new NSUrl(urlString);

        NSUrlRequest request = new NSUrlRequest(url, NSUrlRequestCachePolicy.ReloadIgnoringCacheData, 3);

        NSData data = NSUrlConnection.SendSynchronousRequest(request, out NSUrlResponse response, out NSError error);

        NSString result = NSString.FromData(data,NSStringEncoding.UTF8);

        if(result.Contains(new NSString("Success")))
        {
            return true;
        }

        else
        {
            return false;
        }

    }
  }
}
<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict> 
using System;
using Java.Lang;
using Xamarin.Forms;

[assembly: Dependency(typeof(IsNetworkAvailableImplement))]
namespace xxx.Droid
{
  public class IsNetworkAvailableImplement:INetworkAvailable
  {
    public IsNetworkAvailableImplement()
    {
    }

    public bool IsNetworkAvailable()
    {
        Runtime runtime = Runtime.GetRuntime();

        Process process = runtime.Exec("ping -c 3 www.google.com");

        int result = process.WaitFor();

        if(result==0)
        {
            return true;
        }

        else
        {
            return false;
        }
    }
  }
}
bool isAvailable= DependencyService.Get<INetworkAvailable>().IsNetworkAvailable();

if(isAvailable)
{
  Console.WriteLine("network is available");
}

else
{
  Console.WriteLine("network is unavailable");
}

help you fix your problem The LoRaWAN node does not need any other communications channel aside from LoRaWAN, of course. Would not make any sense otherwise. ;-)
The gateway however does need a connection to the server application that is to be used as a central instance for your use case. Usually this is an existing LoRaWAN cloud service such as The Things Network (TTN) with your application connected behind, but in theory you could connect the gateway to your very own central, making your whole network independent. This is possible because LoRa uses frequency bands free for use (ISM bands) so anyone can become a „network operator“. The TTN software is available as Open Source, for example.
