ERROR: RTMP_ReadPacket, failed to read RTMP packet header

@nostromo

i think the forum has a problem!!!
it only shows a portion of the parameter?

the right playpath is that here...

and not this

-y "stream237?87"

I would be very happy if Admin control that

It's a great pity, but it isn't working for me. I fine out the current playpath value via Wireshark or extract it from HTML code and add into the command, but I receive the same error.
I already compiled latest version rtmpdump from source (OS: Ubuntu 14.04 amd64, Asus K53E, latest version of Google Chrome). I trying use rtmpdump in my Windows XP installation on VirtualBox. Nothing helps me. I have the same ERROR: RTMP_ReadPacket, failed to read RTMP packet header anywhere. I don't know what's the reason of the error.
Log files are attached (I use -z option for extended debug information).

example
use ip usa

$ rtmpdump -r "rtmp://ua4.parom.tv:1935/stream/" -a "stream/" -f "WIN 13,0,0,214" -W "http://america.parom.tv/player.swf" -p "http://america.parom.tv/ru/ort" -y "$(curl -s http://america.parom.tv/ru/ort | grep -Po "file=\K[^\&]*")" -o t.flv
