My new Picoreplayer not found

I have just migrated from LMS on my ReadyNas to LMS on a PI3+. Everything worked fine before I went on vacation.
Now I can't see my Picorelms ???? I can see it on my network with correct ip address, and PCP main page is available, and shows that LMS is running.

But I can not select piCoreLMS on my players ??? It just is not there as a Library anymore ????

When I put in the ip:9000 in my browser then I get ERR_CONNECTION_REFUSED

I have tried to restart everything Router, NAS, Pi


Any clue what has happend..... ??
