PHP. Unable to read SOAP server response. MTOM?

Question

PHP

There is a request to the web services server via SOAP. Everything at first glance usually - an envelope with some data. Through SoapUI requests are executed, responses are received. But as soon as it comes to requests and processing responses through PHP, then the problems begin. The native PHP SoapClient can't read the response, it just hangs. Can't get it to work at all. There have been attempts to simulate SOAP requests via cURL\Guzzle, but alas, the result is the same.
Screenshots below. There is a suspicion that this is MTOM , but I'm not sure.
Please, if someone has experience or someone knows what could be the problem, suggest a solution. I guarantee my gratitude.

What are these fragments? How to make SoapClient work fine?

Answer 1

Hello!
1) Is the cache enabled?
2) Is the timeout set?
3) At least getfunctions works?
4) I would also like to see the soapClient call itself on php
