Microphone capturing doesn't work on dedicated server - actionscript-3

Question

I'm trying to stream audio from browser via rtmp. I use flash api for that. And everything works perfect on localhost. When I'm trying to record the sound from browser on dedicated server it's says to me, that the client (me) haven't allowed the capturing (microphone.muted is true) from my microphone in browser, but I did allow it after first request and it's still allowed in the settings. Any idea?
