Cause

Conga is unable to communicate with Salesforce.

What To Do

  • Ensure “Lock Sessions to IP Address from which they originated” is disabled (Setup > Administration Setup > Security Controls > Session Settings).
  • Verify that the Session Timeout value is at least 30 minutes.
  • Ensure the Conga Composer URL contains an “&Id=” parameter and that it is set to a valid Id.
  • Don’t try to “Preview” a Conga Composer button. You must click it from a Salesforce record.
