IIS page is loading in the web browsers instead of PrinterOn cps page (http(s)://PrinterOnServerAddress) - c06378097

This is due to Web Server (IIS) role being installed on PrinterOn server which is against PrinterOn server requirements.

PrinterOn uses Apache Tomcat for its web services and having IIS installed on the same server will create port conflicts between the two web services.

Solution 1: Remove/Uninstall IIS server role from server manager under remove roles and features wizard

Solution 2: Stop and disable "World Wide Web Publishing Service" from Windows services
