Shipping fails at random times across several carriers at once, and works again for a while only after you close, restart, and log back into Shipstore. This is a Shipstore server-side problem with how carrier sign-in tokens are refreshed. Restarting is only a temporary workaround; report it to support so the backend fix can be confirmed for your site.

Problem

At random times during the day, shipments will not process. Shipping resumes after a restart and re-login, then fails again a short time later. It is not tied to one carrier. There is no single error string; the message can appear as any of these:

Invalid Authentication Information

Object reference not set to an instance of an object

One or more errors occurred

Apigee Access Token Expired

Cause

A Shipstore server-side issue with refreshing carrier sign-in tokens causes sign-in failures across every carrier at the same time. A restart re-establishes the tokens for a short time, which is why shipping works briefly and then fails again. Because the problem is in the shared sign-in path and not in any one carrier account, re-registering a single account does not fix it.

How to check: the failures hit more than one carrier at once and clear only for a short time after a restart. That pattern separates this from a single-account username and password problem.

Fix

  1. Confirm the pattern: the failures are intermittent, hit more than one carrier at once, and clear only briefly after a restart or re-login.
  2. Use restart and re-login only as a stopgap to keep shipping in the meantime.
  3. Do not re-register your carrier accounts to try to fix this. That addresses a different problem.
  4. Email support@shipstore.com to report it and ask whether the backend fix has reached your site. Include the carriers affected, the exact error text you see, and the times of day it happens.

What you should see

After the backend fix is applied, shipping runs continuously without the random sign-in failures and without repeated restarts.
