I also checked this link but its not helping as i am getting this error within 1 min and server timeout is more than 1 min.
Could be some issue with network.
Can you check if everything it´s good?
- please work with your company/project tableau server administrator in setting up the performance monitoring and checking the server logs to identify the root cause of issue.
- secondly you can run checks like tracert commands to check the network yourself.
- last option would be to raise a ticket with tableau support if you are not able to figure out anything.
