Need help from Angular Universal developer + server professional

Hello,

I have 2 problems on a project I am currently working on.
First problem is: I cannot fetch a token from server for local storage
Second problem is: I have an issue with a SOAP query to an API. My request seems to be correct according to the cookbook of the KBO Open Data Web Service (the API) as well as their support team, but I still get the following error: [message:protected] => A security error was encountered when verifying the message.

Here's also a functional request sent to me by support team:
