How do I fix the 'authorization token expiry' error when downloading GSTR-2A in Busy?

Busy's help centre suggests six things in order: log out and log back in, check the date and time settings, clear the cache, reset the GST portal password, check for Busy updates, and check the firewall settings. The error means the session token used to reach the portal is no longer valid, so most fixes force a fresh login.

Steps

This is the order Busy's own FAQ gives. Retry the GSTR download after each step instead of doing all six at once, so you know which one fixed it.

  1. Log out of the GST connection in Busy and log back in with a fresh OTP.
  2. Check the date and time settings of the computer.
  3. Clear the cache.
  4. Reset the GST portal password if the saved one may have changed.
  5. Check for updates to Busy and install the latest version.
  6. Check the firewall settings so Busy can reach the GST portal.
How Charter AI does this

Charter AI works from the GSTR-2B file you upload, so an expired portal session in a desktop tool does not stop a reconciliation. Download the file from the portal, upload it with the purchase register exported from Busy, and the mismatch review starts from there.

FAQs

What does authorization token expiry mean?

It means the login token Busy holds for the GST portal has lapsed, so the portal rejects the download request until a new session is created.
