Music not streaming from work, but is ok from home

[Frank2808]

Hi guys, Subsonic had been working great for me for about 2 years as a way to listen to my music collection from work. Recently, I have been having issues. The Subsonic site loads and I'm able to select tracks etc but when I click play the light grey bar shows that the music had started downloading but the song wont start playing. This is almost certinally a change in network policy at work.. any ideas on how I can trouble shoot this?
