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 sessions through the tsm configuration set Options vizqlserver.protect_sessions, which is set to true by default. Because Tableau Server is configured for trusted authentication, you might not need this level of protection. To disable this option, you can use tsm configuration set Options to change vizqlserver.protect_sessions to false.
