When you open an Autotask Ticket through Rocketship (using the “ticket” button), you might not be able to download attachments.

This happens because of how Autotask’s JavaScript behaves when tickets are opened through their ExecuteCommand API.

Solution

Use Ctrl + Click (or Cmd + Click on Mac) on the attachment link.
This forces the link to open in a new browser tab, which resolves the issue in most browsers.
