App/services UI not opening in browser windows

Connecting to start9 os via local network from a windows 10 laptop, can log in to start9 ok , not able to open UI of services in the browser window of Mozilla Firefox

Please search the forum before creating new topics (and do not ask more than once please) - this is definitely a problem with Bonjour, reinstall and it will work -
