dns multisite subdomain redirection to an older, seperate wp blog

I am currently using the newest freebsd 64 bit system.
I set up the multisite for my website – “digsite.cat” and I decided to make subsites that would be music.digsite.cat etc~
so I did vi digsite.cat.db and added the following stuff
www A 37.59.20.16
scary A 37.59.20.16
music A 37.59.20.16
technically everything would be ok, but on the same server I also have a wordpress blog “donosiciele.pl” and it was the first blog installed on my server. After the VI changes went into the internet I checked https://www.music.digsite.cat and I got redirected to donosiciele.pl even though I have a multisite running; I have a correct entry in dns, and I added a subdomain via wordpress “MUSIC.digsite.cat”
