Playlist folder empty

Hi, I need an help to determine a problem.
My Serviio is installed on Centos 6.5, ffmpeg 2.2.1 with --enable-librtmp.
I am successfully using Serviio to watch movies and youtube channels.

I get the error message, but, as you can see in the following attachment, ffmpeg can access the stream correctly.
Can you just give me an hint where to investigate?
Thanks.
