SOAP PHP fault parsing WSDL: failed to load external entity?

Question

I\'m trying to run a web service using PHP & SOAP, but all I\'m getting so far is this:

(SoapFault)[2] message which states: \'SOAP-ERROR: Parsing

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
