Liquidsoap Won't Start - and other 2.5 Problems

    Hi there.

    I administrate my school's web radio station.  We recently upgraded to Airtime 2.5 and have been having problems since.

    Essentially, we use a program (edcast) on a studio computer to send soundboard output to the master source mount on our Ubuntu server, which hosts icecast and airtime.  

    Since the update, edcast will not connect to the server.  No passwords have been changed.  

    However, if I run "sudo dpkg-reconfigure airtime", edcast will connect just fine.  I must then change my apache vhosts files to move the actual airtime UI to a different port, since our blog runs on :80.
    When I do so, we can no longer connect to the master mount.  

    Below are some terminal outputs.

    My icecast.xml passwords match those in my liquidsoap.cfg, which are both the passwords set with the -reconfigure airtime.
    My vhosts sets airtime to port 5080.  I also edited my airtime.conf to reflect the port change.

    Any idea what's wrong? Thanks for any help.

    SOLVED

    I ended up figuring it out myself after reading about 20 pages of old support threads.  

    I was correctly editing my vhosts and airtime.conf files, but I forgot to edit /etc/airtime/api_client.cfg to reflect the port change as well. 

    Altogether, when changing the port airtime operates on you must check the passwords and/or ports in:
    /etc/airtime/airtime.conf
    /etc/airtime/api_client.cfg
    /etc/apache2/sites-enabled/airtime-vhost.conf
    /etc/icecast2/icecast.xml

    Then I restarted liquidsoap and everything worked again.

    Hopefully this will help someone googling this problem in the future.
