I´m facing an error trying to run a Qlik web Mashup in its internal Qlik server (November 2019) (it is not an external server)
The problem is that ROOT API qlik methods are not working
https://help.qlik.com/en-US/sense-developer/February2021/Subsystems/APIs/Content/Sense_ClientAPIs/Ca...
The screen shot below is with OpenApp() method, but also are failing other methods like getAppList()


But RootApi at least seems to be opened , but it is failing to initiating any method

On network the only resource that has failed to be retrieved is csrf token
