SocketException (0x274c)

Question

I used html agility pack to implement one site_search module. It worked in the local machine. Then uploaded to server and while debugging in the server(as localhost while debugging through remote desktop) it worked fine . But failed to connect while accessing it through IP address of server. It shows the error in code

" Dim webGet = New HtmlWeb Dim document = webGet.Load(baseUrl) "

The Error details are

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

You probably need to increase your timeouts on your server. 30 seconds goes by quick debugging.

    <system.web>
            <httpRuntime executionTimeout="180"/>
    </system.web>
