An error occurred communicating with the server (403)
If Tableau Server is configured for trusted authentication, you may receive this error after opening a new view in a browser and attempting to navigate back to views you’d opened earlier. Tableau Server provides protection against unauthorized reuse of VizQL she tabadmin set option vizqlserver.protect_sessions, which is set to true by default. Because Tableau Server is configured for trusted authentication, you may not also need to enable vizqlserver.protect_sessions. To disable it, use set to change it to false.
