    Hi. I have error page. (attached file)

    We have four servers. only 1 server has this problem. All settings are same. I couldn't find any differences.

    The report page has just a small circle shape.

    I used default Html5ReportViewer1.html and aspx form which is created by Visual Studio new file menu.

     

    When I use fiddler I got this message with URL /api/reports/clients.

     

    {"message":"An error has occurred.","exceptionMessage":"개체 참조가 개체의 인스턴스로 설정되지 않았습니다.","exceptionType":"System.NullReferenceException","stackTrace":"   

    위치: Telerik.Reporting.Cache.CacheStorage.AddInSet(String key, String value)\r\n   
    위치: Telerik.Reporting.Services.Engine.PersistableCollection`1.NewItem(String newID, Action`1 initializeObject)\r\n   
    위치: Telerik.Reporting.Services.Engine.ReportEngine.RegisterClient()\r\n   
    위치: Telerik.Reporting.Services.WebApi.ReportsControllerBase.RegisterClient()\r\n   
    위치: lambda_method(Closure , Object , Object[] )\r\n  
    위치: System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.<>c__DisplayClass13.<GetExecutor>b__c(Object instance, Object[] methodParameters)\r\n   
    위치: System.Threading.Tasks.TaskHelpers.RunSynchronously[TResult](Func`1 func, CancellationToken cancellationToken)"}

    This server has more web sites. but all of them have same problem.

    by the way. /api/reports/formats was ok.

    I am having the same problem in just one of our servers. Did you find a solution about the problem it would be really helpful if you could share?
