Hello Alex,

Thank you for the provided images.

According to the description of the problem, it seems that you are falling into the first case of the described in Report is unavailable or session has expired error message article problems which is an expired session. As with all such cases (not only Telerik Reporting specific), you have to either refresh the page or increase the asp.net session's timeout.

Another approach is keeping the Session alive is to place some kind of a Timer Control that will make a periodic request to the server and will reset the Session's expiration time.

Additionally based on the second image, I believe that you using the ASP.NET Web Forms Report Viewer which obsolete as of Telerik Reporting Q3 2015, our recommendation is to use the latest web forms report viewer - HTML5 ASP.NET Web Forms Report Viewer for web projects.

Details on how to add HTML5 Viewer to the project are available in the following articles:

•  How To Use HTML5 Report Viewer in an application
•  How To Use HTML5 ASP.NET Web Forms Report Viewer

Please let me know if you have any other questions or need further assistance.
