Hi, during a training for PC 1.2.1 we faced the message "ooops! we are unable to connect to your print server due to Username / password mismatch (SRV0001000).
This message indicates that the Designer is unable to authenticate itself to the Server. The authentication is on by default, with the credentials being ol-admin/secret , but if you’ve changed that in the Server Configuration dialog, it also needs to be mirrorred in the Connect Preferences screen (PReS™ Connect 1.3 User Guide - Print (General) Preferences). I think this is probably the most likely cause of this problem.
