Dear, we need urgent support, since the Qlik Sense server of the client in Chile has been presenting time-out problems since its installation.
We thought it was a minor problem but the time-out for users is a little less than 2 minutes. This happens only with the Chrome browser and that is the official browser of the client. We are in the delivery stage and users have been affected their Qlik Sense user experience due to the time-out.
1.- The first image shows one of the panels after a filter selection and that was at 13:01 pm:
2.- The second picture shows the time-out and that was at 13:03 pm:
3.- In QMC the time-out was defined for 30 minutes:
Qlik Sense uses web sockets. If a websocket session is stopped this error shows up. Session idle time is a setting which can be controlled by multiple factors which most of them are not Qlik Sense. Here are those i bumped into:
Proxy - if your company uses proxy it has a standart setting to stop session after 5 min of idle
Session Idle time - if for example your environment is setup in AWS environmnet and you have load balancers (ALB or ELB) in front of it there is a setting in AWS configuration you have to change. The same applies to any other load balancer or reversed proxy which you might have in fron of your Qlik Sense
Group policies which overwrite connection setting
