If you use docker there is a chance you get error because of OpenSSL default security level.

You need lower seclevel in /etc/ssl/openssl.cnf from DEFAULT@SECLEVEL=2 to DEFAULT@SECLEVEL=1

Or just add into Dockerfile

RUN sed -i "s|DEFAULT@SECLEVEL=2|DEFAULT@SECLEVEL=1|g" /etc/ssl/openssl.cnf

After that change I can run SoapClient without any additional options

You can verify it by run on container

curl -A 'cURL User Agent' -4 https://ewus.nfz.gov.pl/ws-broker-server-ewus/services/Auth?wsdl

On register client php make sure that the URL that has been passed to SoapClient is accessible from the machine you re executing the code    sClient   new SoapClient  http   127 0 0 1 MyRegistration login wsdl          If 127 0 0 0 does not work you can try using some network IP address and see   Let me know if it still does not fix it for you  I did try with your example and changing path  making it proper in my dev  environment  has fixed same error for me   I would be interested to know if it does not fix it for you

Just had a similar problem trying to use SoapClient  Everything was working fine but in production  sometimes on page refresh  I would get the  SoapFault exception   WSDL  SOAP-ERROR  Parsing WSDL  Couldn t load from     error   I was using the params   new  SoapClient  WSDL  array  cache wsdl    gt  WSDL CACHE NONE   trace    gt  true   exception    gt  0       Removing all the params worked for me   new  SoapClient  WSDL

If anyone has the same problem  one possible solution is to set the bindto stream context configuration parameter  assuming you re connecting from 11 22 33 44 to 55 66 77 88     context          socket    gt             bindto    gt   55 66 77 88             options          soapVersion    gt  SOAP 1 1       stream context    gt  stream context create  context       client   new Client  11 22 33 44    options

The problem may lie in you don t have enabled openssl extention in your php ini file  go to your php ini file end remove   in line where extension openssl is  Of course in question code there is a part of code responsible for checking whether extension is loaded or not but maybe some uncautious forget about it
