nusoap wsdl connection error but in telnet test everything is OK - php

Question

I use nusoap to connect to an URL,
But I cannot connect and I didn't get any error in $soapclient->getError() .
I can connect to that URL via SSH commant and telnet, that URL show an XML data on browser and everything seems to be OK but PHP cannot connect!
I think I have problem in php.ini configuration !
can you help me to solve this problem ?
when I trying to echo $soapclient; I get content :
