Can't access LMS setup page

Hi,
I'm just after installing PiCore Player on my Raspberry 3 B+. It all went well until I came to setting up the LMS Server. When clicking the LMS Tab in the PiCore Player web interface it tries to open a page with the address :9000 which Safari of course says is an invalid address . I've also tried to enter the address 192.168.1.101:900 but then Safari says it can't open 192.168.1.101:9000 because it can't access the server 192.168.1.101.

I would appreciate any input on what might be issue.
