IssueIn Tableau Server versions released in May 18, 2023 to August 1, 2023 (see Tableau Server Releases), the URL that Tableau Server generated so that the Tableau Desktop user can see the published Workbook/Data Source in their browser had a different server address that isn't covered by the SSL Certificate, leading to the site being shown as insecure. The URL of the Tableau Server changed from the DNS of the application to the hostname of the primary node where Tableau Server is installed when a workbook/ data source/ dashboard is published from Tableau Desktop.
Due to this issue, some users are unable to load embedded dashboards, redirected to an incorrect URL after publishing, or bookmarks are no longer working. Tableau Server URLs (ex. workbook, data source, etc.) may fail to load with "IP address could not be found" or "This site can't be reached" message.
