Subsonic server - err_connection_timed_out

Hi everyone,
I've bought a pi 3 a month ago. I installed owncloud successfully with an external hard drive.
I'd like to use a music streaming server instead of google play music.
First I tried ampache, but project seems ended and old.
Then I took a look at Subsonic, which seems to do the job quite well, even though I'd have to pay 1$/month to use it with my android phone.
So I installed java 8, then Subsonic.
But I only can connect to my subsonic server on my Pi via http://localhost:4040.
I get ERR_CONNECTION_TIMED_OUT with chrome browser from my mac on LAN via http://pi_ip_address:4040.
Maybe I've closed too many doors (ports) configuring apache and owncloud. But I can't find any way to solve it.
Any help would be appreciated ^^
Thanks a lot
