The "S4 Session Token Invalid/Expired" error indicates that your IT solution is unable to reach the EU Hub due to an invalid or expired session token. This error can cause disruptions in the communication between your system and the EU Hub.

Solution

  1. Request a New Session Token:

    • Go to your OBP Portal and request a new Session Token.

    • Ensure that the token is updated in your system until a successful refresh occurs.

  2. Verify Token Refresh:

    • After updating the Session Token, perform a Product Pack Verification in the relevant environment.

    • If you receive a Distribution Callback, this confirms that the Session Token has been successfully refreshed.

  3. Preventive Action:

    • EMVO strongly recommends implementing corrective and preventive measures to address and prevent these errors in the future.
