Environment
- Tableau Prep 2018.1.1
- Windows
Resolution
Ensure that localhost (127.0.0.1) is added to the exception list in your computer's proxy settings.To check this, carry out the following steps:
- In Internet Explorer, on the Tools menu (cog icon), select Internet Options.
- On the Connections tab, click LAN Settings.
- If a proxy server is enabled, check the box marked Bypass proxy server for local addresses.
- If Automatically detect settings or Use automatic configuration script is enabled, work with your local IT team to bypass 127.0.0.1 addresses in the local proxy.
Cause
Tableau Prep sends a HTTP request to the Application Layer when it is launched. This HTTP request can be caught by a proxy when localhost has not been added as an exception.Additional Information
