    data engine error 306

    Edwina Hun

      Hi,

       

      I experience slowness when accessing a Tableau extract (about 80 million rows) and sometimes Tableau will throw out an error.

      "<h2>502 - Web server received an invalid response while acting as a gateway or proxy server.</h2> "

      "<h3>There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server.</h3> "

       

       

      At the back end, the Tableau logs shows repeatedly a data engine error 306 message.

       

      Has anyone encountered an error like that and did you manage to resolve your problem?
