How to use this example in a different Cloud

Hi everyone, I am trying to use this example for my own Cloud, but the registration is every time "unsuccessful".
How I was trying to achieve this:

I installed the "core-java-spring" project by compiling the code (https://github.com/arrowhead-f/core-java-spring#quickstart_compile)
After all the building I installed all the .deb from the core-java-spring/target/ directory

Now to the new cloud, I generated new certificates with this project https://bitbucket.org/thingwave/certificate-generation/src/master/ it worked really well, I also installed these with the install script.
I restarted the arrowhead framework with systemctl restart arrowhead-*
Everything worked and I could login in all services via the web interface and swagger.

Back to the client-cpp. I already got Provider and Consumer running for the testcloud. For my Cloud I tried to get the provider ready. So I started to generate new .pem files in keys2 new with the gen_certs.sh from keys (I reconfigured it). After that I had all new .pem files. I tried first to don't change the names of the .pem so nothing in code could go wrong, I also changed the .ini file to point to my localhost arrowhead system.
But its not working and I don't know why.

I also tried to register it with the web access, I used the .p12 of the service and used in the web access with swagger the same request which the provider used in the screenshot and it worked, but I really don't know why the the Provider can't manage it by it self.
Please help
