Possible Causes


Solution 1

To resolve the issue with theWebDavModule, it may be removed from the configuration of the web application (e.g. Web.config)as shown in the following example:

        <modules runAllManagedModulesForAllRequests="true">
            <remove name="WebDAVModule"/>

Solution 2

To resolve the problem when the Get Clients Session Timeout Seconds failing, move the registration of the reporting routes before the default ones, for example:


    name: "DefaultApi",
    routeTemplate: "api/{controller}/{action}/{id}",
    defaults: new { id = RouteParameter.Optional }
