I am facing same issue with multiple machines (Xerox 5855, 5875).
Printer working fine then suddenly weird things start to happen. Secure queue jobs page 1 and page3 will display user list but page 2 remains empty. then we need to click multiple buttons, login, logout and then the queue will show all the users.
When we try to access the webpage it does not respond while we can ping the printer successfully/ we can also give prints. then we need to restart the machine and web server is accessible.
is this anything to do with motherboard or network card?
Note: printer is running with latest firmware WorkCentre_5845-5890_system-sw07319000903700
