Discussion Board for collaboration related to QlikView Deployment.
Since the migration from Qlikview 8.5 to Qlikview 9, we have a problem. All the users who use Internet Explore with plugin have a message after a few minutes "Lost connection to server".
Could you help us ?
Did you check the settings in the control-panel: Session-Time or Session-Timeout
Is the 8.5 server still on line? if so shut it down and see if the problem goes away. The servers maybe trying to cluster.
