Configuration for shoutcast

Hey. I try to set mopidy last two days to send audio to the shoutcast server as autopilot.
I tried to use the configuration from the icecast documentation, but it doesn’t work properly with shoutcast (also after setting the icy protocol for shout2send). Is anyone able to submit a valid configuration for shoutcast (in my case version 2.5.5)?
on config:

output = lamemp3enc ! shout2send protocol=icy async=false mount=18434 ip=my.ip port=18434 password=priv

i have:

 GStreamer error: gst-resource-error-quark: Could not write to resource. (10)

on any other: can’t connect to server
