I supplied same credentials in my program but it fails with HTTP 407 error. Here is my code: HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL); IWebProxy proxy = WebRequest.GetSystemWebProxy(); CredentialCache cc = new CredentialCache(); NetworkCredential nc = new NetworkCredential(); nc.UserName = "userName"; nc.Password = "password"; nc.Domain

= "mydomain"; cc.Add("http://20.154.23.100", 8888, "Basic", nc); proxy.Credentials = cc; //proxy.Credentials = System.Net.CredentialCache.DefaultCredentials; request.Proxy = proxy; request.Proxy.Credentials = cc; request.Credentials = cc; request.PreAuthenticate = true; I have tried every possible thing but seem like I am missing something. Is it something like, I have to make two requests? First with out credentials and once I hear back from server about need for credentials, make same request with credentials? c# proxy httpwebrequest basic-authentication http-status-code-407 share|improve this question edited Oct 26 '15 at 8:26 Nicolas Raoul 25k34122224 asked Mar 7 '12 at 14:16 rplusg 1,38142143 What authentication scheme does your proxy server require?

Put this in your application configuration file - probably app.config. Visual Studio will rename it to yourappname.exe.config on build, and it will end up next to your executable. If you don't have an application configuration file, just add one using Add New Item in Visual Studio.

I get the general idea and I can get the code to work by adding myProxy.Credentials = http://stackoverflow.com/questions/2581609/the-remote-server-returned-an-error-407-proxy-authentication-required NetworkCredential("user", "password", "domain"); or by using DefaultCredentials in code. My problem is that the call to the web service works in production without this. It seems like there is a non code solution involving Machine.config, but what is it? At the moment I can't get to the production box's machine.config file to see what that looks like. I tried updating my machine.config as follows, but I still get the 407 error.

System.Net Error: 0 : [4811] Exception in the HttpWebRequest#33574938:: - The remote server returned an error: (407) Proxy Authentication Required. We can see in a Fiddler2trace proxy authentication that Internet Explorer does submit the 407 credentials of the currently logged on user, but the HttpWebRequest does not even try. We also see that for HTTP traffic there is no 407 in either request. Only HTTPS traffic was requiring credentials for the proxy. Resolution By default the Proxy object does not supply the credentials of the Currently Logged on User. You can fix this proxy authentication required by: 1.Supply the credentials of the Currently Logged on User to the Proxy object similar to this: Copy Code:

Comments (131) | Share The remote server returned an error: (407) Proxy Authentication Required. This is a very common error message when you try to get a resource on internet through your application. Why you getting this error from your application not from explorer. The reason is very simple either you use LAN that requires proxy setting or you use proxy server. Example : DataSet myds = new DataSet(); //Set the system proxy with valid server address or IP and port. System.Net.WebProxy pry = new System.Net.WebProxy("172.16.0.1",8080); //The DefaultCredentials automically get username and password. pry.Credentials = CredentialCache.DefaultCredentials; GlobalProxySelection.Select = pry; myds.ReadXml("http://msdn.microsoft.com/netframework/rss.xml", XmlReadMode.Auto); myds.WriteXmlSchema(@"c:\\f.xml"); this.GridView1.DataSource = myds.Tables[2]; this.GridView1.DataBind(); Posted on Saturday, August 11, 2007 2:30 AM Exceptions , .Net , Microsoft Servers | Back to top Related Posts on Geeks With Blogs Matching Categories DotNetters–it’s time to graph up .NET Semaphores for better distribution of work items a... .Net Blogs that proved to be invaluable .NET What killed my message loop? .NET AngularJS2 on ASP.Net Cor
