If you use https, SOAP modules need to configure with openssl, otherwise will be catch a error like:
SOAP-ERROR: Parsing WSDL: Couldn't load from url
Requirements
This extension requires the libxml PHP extension. This means passing the --with-libxml, or prior to PHP 7.4 the --enable-libxml, configuration flag, although this is implicitly accomplished because libxml is enabled by default.

Typically, on microsoft windows(sometimes linux), we got "I/O warning : failed to load external entity" and "Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from somewhere".
only xml lib is not enough, php-soap also need cURL, and openssl if you wants connect to https
