Environment
iPrint Appliance 5.x (Upgraded from iPrint Appliance 2.x)
Situation
RPC errors when attempting list printers from the :9443 page after upgrading to iPrint Appliance 5x. The Appliance at one point was iPrint Appliance 2.x. Creating a CSR using the certman.sh tool completes without error, but the server certificate is not created. This causes SSL printing to fail.
Cause
The iPrint Appliance upgrade continues the old CA authority which still uses SHA1 signature algorithm. The causes problems with the port 9443 page listing printers and problems with certman.sh creating a CSR.
Resolution
Recreate the CA authority
Additional Information
The iPrint Appliance is now running with self-signed certificates. If a 3rd party certificate is desired, create a new CSR, send the CSR to the external CA, and upload the external certificates using the steps listed in the documentation.
