I have an iPrint Appliance 1.0.377.2 that the original self-signed certificate expired. Everything works as far as printing and installing printers from a browser but I can no longer manage printers (anything to do with iManager).
I have tried to create a new self signed certificate (key pair) with only the required info (DNS name matches appliance name, everything else is default) and rebooted the appliance but still the error persists:
IPP Error: 0xF0191
HTTP Error: 401
What am I missing?
