Update your code to the following: var wc = new WebClient(); wc.Headers.Add ("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)"); TaskCompletionSource

The same page would render 500 internal server fine using a browser. It was only once in a while it happened.I thought it might have something to do with the WebClient class so I tried using an HttpWebRequest and HttpWebResponse instead, but the result was the same. Then I started Fiddler to construct requests and tried out different HTTP headers. This let me to the problem and the solution.The problem was that some websites use certain headers without checking if they exist or not. In this case it was the Accept-Encoding and Accept-Language headers that were missing from my request. The solution is the method below.///

I was trying to debug the application by putting System.Windows.Forms.MessageBox.Show() whereever I suspected the problem to be and then started the server in debug mode. It seems that the below line is the culprit - byte[] responseArray = mWebClient.UploadValues(URL, "POST", paramList); paramList is an instance of NameValueCollection and URL is a valid representation of the URL to the GUI I want to access in String format. This is the stack trace of the error I get - System.Net.WebException: The remote server returned an error: (500) Internal Server Error. at System.Net.WebClient.UploadValues(Uri address,String method,NameValueCollectionData data) at System.Net.WebClient.UploadValues(String address,String method,NameValueCollectionData data) . . .
