Extension appears gray in tableau online but not in desktop

• Check the whitelisting in Tableau settings. The extension url needs to be whitelisted to be able to run in a Tableau online dashboard.

• Is the extension running behind a proxy? Be sure the proxy is not adding CSP (Content Security Policy) Headers to the request. To find out if this is the cause, open the developer tools in your browser and open the console tab. When there are red messages complaining about Content Security Policy, then this is the problem.

Running behind a Reversed Proxy and wrong domain in the trex file

• If you are running behind a reversed proxy and the domain in the trex is therefore showing the domain of the server instead of the public facing domain follow these steps.

• Open the config.yaml file in your installation folder.

• Add or update the host variable to the public facing domain.

• Restart the application.

• Download the trex file from yourdomain.com/trex
