When Loading A View "502 Server Error" With HTML Code Is Displayed


Published: 13 Mar 2020

Issue

When loading a view, a Tableau Server dialogue box will appear, possibly stating a "502 Server Error" has occurred. There will be raw HTML code in the response.

Example:

User-added image

Environment

  • Tableau Server 
  • Load Balancer or Proxy

Resolution

Check any load balancer or proxies in the environment for timeout values and increase them. 

Cause

If the timeout value is set lower than it takes for Tableau Server to respond with bootstrap, the load balancer will return an error.
