Hi Roy,
I am using 9.1 and it is working.
this 127.0.01 is the dashboard B1i Administrative Logon.
and it should be the same as your dashboard login when you click from the general settings inside sap business one.
If the URL is giving you a different IP or it is pointing to the server name, then go back to your SLD maintenance and update the correct settings. (database, xcelsius and hanyxcelsius).
Hope this helps.
Regards,
D
