I've been experiencing the same issue (as DM or tested as Player), where... Jukebox (and that Link in Steve's post above) does NOT play on my Mac OS 10.10.2, Google Chrome Version 40.0.2214.111 (64-bit). But it does play on my Windows 7 PC, side by side (also Google Chrome Version 40.0.2214.111 m). Same username, same WiFi connection, different computer. So as Steve said, it seems to be something set wrong on 1 of my laptops, and may be the same for Kiloku. When I click the link (Steve's post), on my Mac, I get this: 502 Bad Gateway The server returned an invalid or incomplete response. Same for you, Kiloku? On my Windows 7 computer, it starts playing the song as expected. Additional Notes: It's been not-working (read: silent jukebox) on my Mac for a couple weeks. Just now getting around to troubleshooting it, and tested and found it works (same campaign, same login, same WiFi/ISP, different laptop). So, "something locally to your computer is blocking that content from playing" -- Steve. Any ideas what could be blocking it? I don't have any Extensions or anything non-default set up to block, and, Jukebox was working on this computer up until recently. In the interim I changed nothing except for letting Chrome update automatically. I know I last used Jukebox extensively on my campaign in December and it worked fine on my Mac then. As my issue seems the same as Kiloku, I'll join this thread, rather than starting anew.
