My iprint applaince started acting like iuts certificates were expires, Could not read the list of printers then got the RPC error. I renewed the certificates, with the regenerate.sh script, upon reboot I could see all the walk up printers, all the printers were green, but no print job would come out and the print diaglog freezes from windows and from ANY browser. I rebooted the server again, and now RPC is NOT communicating again. Never have seen this issue before, no one in my organazaitn can print. Not sure why this is happening. Can anyone give me any guidence. Have been running the iprint server for years I have never seen this before.
