Ambiente

Tableau Server
Tableau Desktop
Windows Server
Proxy server
F5 Load balancer

Resolução

1. If an external load balancer such as F5 is used, check with the network administrator to verify and modify the HTTP profile setting in F5.

2. Otherwise, run the following TSM commands on Tableau Server. If Tableau Server is running on a distributed environment, run the commands on the initial node in the cluster and inspect the results:

tsm configuration get -k gateway.trusted
tsm configuration get -k gateway.public.host
tsm configuration get -k gateway.public.port

The results from above commands must correspond with the appropriate tsm configuration set options described in the Tableau Help documentation Configuring Proxies for Tableau Server.

Causa

Tableau Server was not properly configured to work with proxy server and/or load balancer.
Or,
F5 Load Balancer HTTP profile was not configured correctly.
