No Available Qlik Sense engine was found - App still accessible

We are having an issue where some of our users are experiencing an error when opening an app from the hub:

No available Qlik Sense engine was found. Refresh your browser or contact your system administrator

Despite having this error pop up, if they click "Go to the hub" and open the app again, they are able to view it with no issues. Is there a way to prevent this error popup?

 

We have tried restarting services and the server with no luck. We are on Qlik Sense September 2019: qliksenseserver: 13.42.1

Single or Multinode, how many engine do you load balance to?

We are currently in a single node dev environment.

Do the issue occurs randomly, consistently (as of right now)? one app, few apps, all apps? Some end users, all end users? Does the shared folder where apps are store, is a local drive, or NAS or SAN?

We are currently experiencing this issue consistently with about 3-4 of our users, who are all ContentAdmins. Apps are located on a local drive.

We noticed the users having the issue are Analyzer capacity users. In the log details of the operations monitor, we noticed this pattern of events every time the user tried to access the app, always in the same order. 

Analyzer access granted for user

Access was denied for user

Access to app allowed with access 'AnalyzerAccessType'

so should they have a capacity license or do they have a token assign? What kind licensing are you assigning to those users?

They have Analyzer access, not Analyzer capacity. 

Giuseppe_Novello

okay, just want to confirm this professional and Analyzer tokens only, there is not capacity license? 

Yes, Then Analyzer should not have any issue opening apps, the only limit they have is to create apps:
https://support.qlik.com/articles/000048868

however, the error it is returning it is puzzling, since if it is license related it won't complain about missing engine, it will complain about "too much parallel sessions" or " no token assign".

To be honest, this need deep digging, so I would suggest to open a Qlik support ticket ( if you have direct maintenance agreement)
