DRM Error: 3305[ServerConnectionFailed]  and Error loading metadata file:Error #2048

I am using the sample player in Adobe Access 4_0 SDK to play the encrypted video on FMS 5.0.

1) When trying to play the " http://.../vod/WorldCup.mp4"  file and get the error "DRM Error: 3305[ServerConnectionFailed]  Load http://.../vod/WorldCup.mp4 "

2) switch TVP mode. try to "Load DRM Metadata" and get the log " Error loading metadata file: Get URL:http://.../vod/WorldCup.mp4.metadata:Error #2048"
