[mp3cast~]'s output on the pd-window should give you a hint, whether it
could connect to the icecast-server or not. if nothing tells you, that
connection failed or something like that, i would assume that it could
connect correctly and that the problem might be with the connection
between client-app and server. 

some random possible problems, that come to my mind:

-did you try to connect the client on the right port (e.g.
http://yourhost.com:8080/yourstream.mp3 ) ?

-is the port not blocked by a firewall?

the only thing i know, is that before the [connect(-messages all other
settings-messages should be sent.

hm.... my icecast-server (v2.3.1) has a configuration-file called
icecast.xml, where the password is written in plain-text (the file is in
xml-format). so no makepasswd and stuff is needed. i don't know if
icecast.conf works differently.

yes, you can send the messages in a certain order in pd and yes, it DOES
matter when sending the settings-messages to [mp3cast~]. first set all
settings like passwd, mountpoint, bitrate etc and after this send the
[connect blabla.com 8080(-message. you could put all settings-messages
in one single message-box, separated by a ',' like for example:

[name streamname, mountpoint yourstream.mp3, icecast2, password
yourpasswd, mpeg 44100 128 1 4(

good luck
