Opening a Sense App on the Hub returns "An error occurred The app you specified could not be found." The Qlik Sense Engine logs fail at "Open App" with "Could not find app". Reload tasks in the Management Console fail.
One of the causes are if Engine services are restarted before Repository service. Ensure you restart services in the right order as specified in Manual start
section of the following link:Manual start
1. If running Shared Persistance or June 2017+, verify that the applications are stored in the shared folder of the ServiceCluster.
To review the ServiceCluster location, open the Management Console, navigate to Service Cluster in the left hand menu below Configure System.
2.If the applicatoins are available, verify that the shared permissions of the QlikSense service account are correct, and that no network connectivity issues prevent the services from reaching the shared path.
3. "max_connection" of Repository Database reached upper limit. Increase "max_connection" (default value is 100) in postgresql.conf to higher value. e.g. 100 x number of nodes at least.
Stop all services
4. Restart all the services once the above change is performed as mentioned in postgresql.conf file.
