# 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](https://help.tableau.com/current/server-linux/en-us/cli_configuration-set_tsm.htm) `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](https://help.tableau.com/current/server-linux/en-us/cli_configuration-set_tsm.htm) to change `vizqlserver.protect_sessions` to `false`. Beginning in 2024.2.0, Tableau Server always prevents VizQL sessions from being reused after the original user signs out.
