SoapServer failed to open stream: Cannot assign requested address

Hello, I am doing migration to another server (on docker).
Now I have this problem:

SoapServer::SoapServer(http://example.com): failed to open stream: Cannot assign requested address

/var/www/test.test/yii-framework-1.1.10/web/services/CWebService.php(156)

156 row:

$server=new SoapServer($this->wsdlUrl,$this->getOptions());

when I am doing request via SoapUI.
The request is 100% correct
Where can be the problem?

I have installed php5.6-soap and tried to change php.ini file like here , but it still does not work so far…(

Thanks for Your ideas and advice :wink:
