Problem with GetSockError

[gorilla.maguila]

Every time I try to dump:

rtmpdump -r rtmp://31.220.0.138:1935/redirect/actionx -W http://p.jwpcdn.com/6/8/jwplayer.flash.swf -p http://www.eucast.tv/embed.php?le=actionx --live --debug

I get a GetSockError:

DEBUG: Protocol : RTMP
DEBUG: Hostname : 31.220.0.138
DEBUG: Port     : 1935
DEBUG: Playpath : actionx
DEBUG: tcUrl    : rtmp://31.220.0.138:1935/redirect

ERROR: RTMP_Connect1, handshake failed.
DEBUG: Closing connection.

But right after this fails I try again to dump with the same parameters:

rtmpdump -r rtmp://31.220.0.138:1935/redirect/actionx -W http://p.jwpcdn.com/6/8/jwplayer.flash.swf -p http://www.eucast.tv/embed.php?le=actionx --live --debug

And magically works...

So first attempt fails and second attempt works, and this happens everytime. I've tried changing my IP, trying under other machines to check if I'm somehow geoblocked with the same two attempts result.

Can anybody enlighten me?
