The issue occurred due to the expiration of a system token from the Print Gateway application, which resulted in certain clients receiving 401 errors during print jobs. To resolve this, clients had to reinstall the Print Gateway, forcing the authentication engine to issue a new token. A corrective action is already planned for the next release. We will be introducing enhancements to our identity provider that will include improved token management for the Print Gateway application, ensuring that tokens are refreshed and valid in all scenarios without manual intervention.
