Good evening, I have a reporting services installation on a backend server and a web application with asp.net technology on the frontend server.
The web application is developed with .net framework 4.7.2 and report viewer is version 15 downloaded from nuget from Visual studio 2019.
The web application with report viewer displays the report well but the export does not work, in any format. The error on the page ".../Reserved.ReportViewerWebControl.axd?ReportSession=l4br..." is "404 - File or directory not found.".
Do you have any idea how to solve the problem?
Thanks in advance
