when you connect to SQl server. this window will pop up:
Please provide your fully qualified server name and port number.
Connect to the data source using the fully qualified domain name. For example:
you can provide your authentication details.
The computer running Tableau Desktop is unable to resolve the server name to an IP address, or the port the data source uses to communicate is blocked.
when i look at your error description you are using this:
Thiis need to be used when you want to access your postgre sql of tableau.
using command line you can run these commands to see whether you are able to access the particular server or not.
- Go to /Applications/Utilities.
- Open Terminal, and then type
please check you have connect permission in your server.
Thanks for your support.
I use Windows Authentication so Tableau Server don't connect database SQL.
When i use a specific username and password SA, it's OK.
