Reporting Service Auditor always throw this exception, what can I do for that error?
If there is a timeout warning, you need to modify parameters in Web.Config file to allow SQL Reporting Services Auditor to check your report server not timeout.
CheckParameterTimeout is the timeout value for checking report parameters.
RenderTimeout is the timeout value for rendering report.
The web.config is located in the virtual directory folder. This is typically C:\Program Files\SSW SQL Reporting Services Auditor\WebApp\Web.Config
