Streaming with ffmpeg to Zony.tv problem

[hakursa]

Hello,
I'm using ffmpeg to stream through my server and every site I tried to stream to is working like charm, but only the best one isn't working - zony.tv

I have this command to stream:
ffmpeg -re -i http://CDN12_eu.sababatv.com:80/C18/...8-67a436fdefbb -framerate 25 -vcodec h264 -video_size 720x480 -c:v libx264 -preset veryfast -maxrate 1000k -bufsize 2548k -pix_fmt yuv420p -c:a libmp3lame -b:a 96k -ar 44100 -f flv "rtmp://cdn.pubzony.com/stream/exampled?key=db6c5424&id=3055"

But when I run it in the cmd it's writing to me:
rtmp server requested close
