HTTP GET works in browser, but doesn't with HTTPWebRequest

Title explains it. I am trying to change the password of a webpage programmatically using HTTP Web Request. When I do it through Google Chrome (pasting the uri in the address bar), the password change works. Here is the header I get when I inspect in Chrome.

Remote Address:10.160.70.55:443
Request URL:https://10.160.70.55/cgi-bin/check_user.cgi?Type=basic&Current=78-62-118-112-106-108-56&Password=98-96-102-96-106-96
Request Method:GET

Accept:text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
Accept-Encoding:gzip,deflate,sdch
Accept-Language:en-US,en;q=0.8,fr;q=0.6,ar;q=0.4
Authorization:Digest username="admin", realm="Secure Access", nonce="f3c6fcd9a549a42e9aac22818cb0f5ad", uri="/cgi-bin/check_user.cgi?Type=basic&Current=78-62-118-112-106-108-56&Password=98-96-102-96-106-96", response="cd17523a279f044d086b5bd0245eda0e", qop=auth, nc=0000001b, cnonce="9bd719c27efd9721"
Connection:keep-alive
Host:10.160.70.55

When I try to do it programatically, I receive the OK (200) code, but the password change does not work. Here's my code.

System.Uri uri2 = new Uri(string.Format("https://{0}/cgi-bin/check_user.cgi?Type=basic&Current=78-62-118-112-106-108-56&Password=98-96-102-96-106-96", ip));
                        HttpWebRequest request2 = (HttpWebRequest)WebRequest.Create(uri) as HttpWebRequest;
                        request2.Accept = "text/html";
                        request2.Credentials = new NetworkCredential("admin", "M@ster1");
                        request2.Method = WebRequestMethods.Http.Get;
                        HttpWebResponse response2 = (HttpWebResponse)request.GetResponse();
                        WriteLog(response2.StatusDescription.ToString());

                        response2.Close();

Used fiddler as suggested, and it turns out it was the user-agent header. And thank you for correcting the typo L.B. :)
