title: SSIS Script Transformation Error The remote server returned an error: (407) Proxy Authentication Required
body: <p>I'm using SQL Server and Visual Studio 2019.  I have a SSIS Package that uses a Script Transformation as a source (c#) that pulls data from a web service.  When I execute via Visual Studio on my laptop it all works 100%.  When I deploy to the SSIS Catalog and execute I keep receiving the error:</p>
  <pre><code>Error The remote server returned an error: (407) Proxy Authentication Required
  </code></pre>
  <p>Here is a snippet of my code:</p>
  <pre><code>public class ScriptMain : UserComponent
  {
      string json;
      DateTime epoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
  
      public override void PreExecute()
      {
          base.PreExecute();
          ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;
          
          string fullurl = Variables.FullURL;
  
          string url = fullurl;
  
          json = DownloadJson(url);
      }
  </code></pre>
  <p>I'm building the url using a variable (fullurl in the above) that includes all the login and password info.  Do I need to modify this or is it something on the company network blocking it?</p>
