Error "The proxy server received an invalid response..." Loading View

Issue

When you try to open a view on Tableau Server, the view may take a long time to load, and then the following error might occur:

Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request
POST /vizql/w/<WORKBOOK>/v/<VIEWNAME>/<OTHER-INFO>

Reason: Error reading from the remote server.

Environment

Tableau Server
Proxy or F5 load balancer

Resolution

Option 1:

Work with your proxy administrator to increase the proxy timeout interval.

Option 2:

Revise the views so that the total load time on Tableau Server is lower than the proxy timeout.

Cause

The proxy is timing out before the HTTP request for the view returns a response. The appearance of this error indicates that the view is taking at least as long to render as the proxy timeout interval.
