Blank Screen Opening View and VizQL Down

Date de publication: Feb 24, 2026
Description
When opening a view on Tableau Server, users see a blank screen where the view would be.  The rest of the UI might still load.  
The status screen shows that the Vizql server is down, even if the tabadmin status shows it is running.  

In the Vizql logs, you might see some of the following errors:

GenericJDBCException: Could not open connection

Cause

Something is interfering with communication on VizQL's JMX ports (9400-9403).  
Résolution
Disable the JMX ports with the following command:   
For Tableau Server 2018.2 or newer on Windows, and for all Tableau Server versions on Linux:


tsm configuration set -k service.jmx_enabled -v false
​For Tableau Server 2018.1 or older on Windows:


tabadmin set service.jmx_enabled false
