HttpWebRequest "The remote server returned an error: (503) Server Unavailable."

Question

Hello!

I create a simple request to the www.googl.com. But in the cycle it throw exception (The remote server returned an error: (503) Server Unavailable. )

HttpWebRequest myHttpWebRequest = (HttpWebRequest)HttpWebRequest.Create(queryString);
HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
StreamReader myStreamReader = new StreamReader(myHttpWebResponse.GetResponseStream(), Encoding.UTF8);
result = myStreamReader.ReadToEnd();
myStreamReader.Close();
myHttpWebResponse.Close(); 

What reason of the problem? And how to solve this problem?

TIA

Answer 1

This is coming from the Google server, not you.  There's no way to solve it on your end (unless your query is incorrect, and Google throws a 503 in response to this. which I'm pretty certain they don't do).

Use a try/catch to handle the error when it happens, because it will occasionally happen.

Answer 2

I copied your code and tried it myself (using queryString = "http://www.google.com") and had no problems at all. So if this is a message that you're getting consistantly, you might want to try using the tracert command to see exactly what path your request is taking.
