[Linux] When Creating a New Connection from Tableau Server Browser Connecting to BOX Data Source, "Unexpected Error" Occurs

When creating a new connection from Tableau Server browser connecting to BOX data source, the following message occurs:
Error Message:
Unexpected Error: An unexpected error occurred. If you continue to receive this error please contact your Tableau Server Administrator.


  • Tableau Server Linux
  • Using forward proxy to connect BOX data source


This behavior is caused by a defect, ID 1365609, which is currently under investigation.

As a workaround try the following steps instead of creating a connection from the browser directly:
  1. Use Tableau Desktop to connect to BOX.
  2. Then publish the workbook to Tableau Server.


Creating a new BOX connection in 'Web Edit' mode ignores forward proxy configuration on Tableau Server on Linux version.
This issue is under investigation under ID 1365609.
