Playbackrtmp

Hello,
i have two streams in my app using two method of playback.
when i watch a rtmp url like rtmp://host.com/app/streams --> works
now i switch the stream to AVOptions:
rtmp rtmp_app rtmp_playpath etc. --> works
now i switch back to the normal rtmp link (rtmp://host.com/app/streams) it does not work, error: cannot play the video even though i can play the rtmp from log on PC just fine.
any idea why im getting this error?
