Problem
ViewX client fails to communicate with the server and the following error appears “ClearSCADA.Client.SecureSessionRequiredException”.
Solution
One of the common causes of ViewX client not able to connect to the server with error “ClearSCADA.Client.SecureSessionRequiredException” Is that the secure connection is set to false.
A workaround is to edit SYSTEMS.XML manually and change the secure field to "true". The folder can be located by default as follows C:\ProgramData\Schneider Electric\ClearSCADA. Please make sure to close ViewX client and shut down the server before editing the SYSTEMS.XML file.
Change SecureConnection= “false” to “true” as indicated below.
Once the editing is completed, save the changes and restart the ViewX client.
