Printer not Activated -60


I have a customer that have issues for the last few days with when they try and email invoices they get the error " Printer not activated, error code -60" We have done all the normal things of remove printer reinstall printer. The About page of the printer says its "Licensed to Reckon limited"

On some of the Amyuni support pages say that RDS servers need a different license key to work and this is on the RDS server. How do we get the RDS Amyuni keys if thats what needed? This setup has been working for years but last week stopped.

Environment is

Server 2019 RDS.

Reckon accounts enterprise 2022
