Удаленный сервер возвратил ошибку 403 запрещено curse forge

I’ve written an app that has worked fine for months, in the last few days I’ve been getting the error below on the installed version only.

If I run the source code in VS everything works fine. Also, the .exe in the bin folders work fine. It’s only the installed version which generates the error, if I recompile and reinstall I get the same error.

I’m a bit stumped as to what’s causing this and hoped for a few pointers. It seems to be a WebRequest response through IE is not being returned but I’m stumped as to why it works fine in VS without any errors. Are there any new IE security measures/polices that may cause this?

Things I’ve tried so far include:

• Disabled all AntiVirus & Firewall
• Run as Administrator

The Exception:

Exception: System.Windows.Markup.XamlParseException: The invocation of the constructor on type 'XApp.MainWindow' that matches the specified binding constraints threw an exception. ---> System.Net.WebException: The remote server returned an error: (403) Forbidden.

EDIT:

This is installed as a standalone app. When I’ve run as Administrator, I’ve opened the program folder and run the exe as administrator rather than the shortcut.

The code that causes the issue is this

private void GetLinks()
{
    //Navigate to front page to Set cookies
    HtmlRequest htmlReq = new HtmlRequest();

    OLinks = new Dictionary<string, List<string>>();

    string Url = "http://www.somesite.com/somepage";
    CookieContainer cookieJar = new CookieContainer();
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);
    request.CookieContainer = cookieJar;

    request.Accept = @"text/html, application/xhtml+xml, */*";
    request.Referer = @"http://www.somesite.com/";
    request.Headers.Add("Accept-Language", "en-GB");
    request.UserAgent = @"Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; Trident/6.0)";
    request.Host = @"www.somesite.com";

    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
    String htmlString;
    using (var reader = new StreamReader(response.GetResponseStream()))
    {
        htmlString = reader.ReadToEnd();
    }

    //More Code

I’m using the Google API on my website. It works
fine from my localhost, but on the live server I get the following
error:

System.Net.WebException: The remote server returned an error: (403)
Forbidden.
at System.Net.HttpWebRequest.GetResponse()
at GoogleUrlShortnerApi.Shorten(String url)

I’m using the code found here:
http://www.thecyberwizard.com/index.php/5/google-analytics-api-in-c-part-1/

And from debugging, I see that the error occurs on the

HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();

command.

Does anyone know what could be causing the error (again, the error
happens only on the server. When I run this code locally on my
computer, it runs fine and retrieves a short url).

I have to turn off billing still I get the following
error:

System.Net.WebException: The remote server returned an error: (403)  

How can I resolve this?

whats wrong in my code?

or is there any other example to get my gmail friends list?

Thanks,

I have created a SharePoint 2016 app (add-in) using visual studio 2019. Everything is what the boiler template provides in Visual studio, so no changes in the code.

I created a self-signed certificate, added it to Central admin, generated the Issuer Id and added that in the web.config.

When I deploy the app, I get the 403 error.

I am administrator in the dev machine.

The remote server returned an error: (403) Forbidden.

What am I doing wrong?

Я написал приложение, которое отлично работало в течение нескольких месяцев, в последние несколько дней я получал ошибку ниже только в установленной версии.

Если я запускаю исходный код в VS, все работает нормально. Кроме того, файл .exe в папках bin работает нормально. Это только установленная версия, которая генерирует ошибку, если я перекомпилирую и переустановить, я получаю ту же ошибку.

Я немного озадачен тем, что вызывает это, и надеялся на несколько указателей. Кажется, что ответ WebRequest через IE не возвращается, но я в тупике, почему он отлично работает в VS без каких-либо ошибок. Существуют ли какие-либо новые меры/меры безопасности IE, которые могут вызвать это?

Вещи, которые я пробовал до сих пор, включают:

• Отключено все антивирус и брандмауэр
• Запуск от имени администратора

Это установлено как отдельное приложение. Когда я запускаю Администратор, я открыл папку программы и запускаю exe как администратор, а не ярлык.
