We have configured Apache Loadbalancer . We have sepearte team for that . But as i far as know , Apache is configured correctly.
Is there any configuration issues that depedns on Loadbalancer in Tableau Server Linux .
I would make sure you have considered everything on the URL above and this one:
Load balancers act as a proxy for Tableau Server, so as long as the load balancer has the correct IP addresses or DNS names to route traffic, it should be fine. Keep in mind that you can only route traffic to the nodes that have all of Tableau licensed server processes.
I would suggest you need to run a full network trace to see why this is happening. It's a networking issue, I believe.
You could try creating a Tableau Support case or you could ask your Tableau Sales Rep for help by getting Tableau Services. They would come onsite and work with your network team and you to figure out the issue and get it working.
