Reprint from Shipment History fails with an unauthorized (401) error

Summary: On a self-hosted (Private Cloud) Shipstore server, reprinting a label from Shipment History can fail with an unauthorized (401) error when the Windows permissions on the label temp folder change. Have your IT team restore access for the account Shipstore runs under.

Problem

A user can no longer reprint labels from the Shipment History screen. The reprint returns an unauthorized or permission error (often shown as a 401). It worked before, and nothing changed in Shipstore.

Cause

This applies to a self-hosted (Private Cloud) install, where Shipstore runs on your own server. The reprint reads the saved label from a temporary folder on that server. If the Windows permissions on that folder change, the account Shipstore runs under can no longer read it, so the reprint fails.

How to check: sign in to the Shipstore server and open the label temp folder under your Shipstore install path (Extras\Downloads\TEMP\PL). If you get access denied there, a permission change is the cause.

Fix

1. Find the label temp folder on the Shipstore server, under your install path: Extras\Downloads\TEMP\PL.
2. Confirm the problem is permissions: open that folder on the server. Access denied confirms it.
3. Have your IT team restore read and write permissions on that folder for the Windows account (application pool identity) that Shipstore runs under.
4. Try the reprint from Shipment History again.

What you should see

The reprint from Shipment History completes with no unauthorized or 401 error.
