HttpException (0x80004005): Request timed out…

Problem

You get this error when displaying a web page in your application:

Server Error: HttpException (0x80004005): Request timed out.

This typically occurs when a server-side code function or macro executes for a period of time longer than the maximum timeout period allowed for server-side code execution.

Solution

Adjust the executionTimeout parameter in your application’s Web.config file.

<httpRuntime
            maxRequestLength="10240"
            executionTimeout="36000"
/>
