Generate new Certificates and connect to server

[AndroidzZ]

Because of a new license I had to reinstall the runtime app again on the CORE. 

After reinstalling the webiq Runtime app on the CORE i seem to lost connection to the server, see:

My IO manager in the desinger can't connect while no settings have been changed in regarding to autentication or endpoint. 

I also checked the Certificates and time of the CORE. it all seems to be fine but still no connection is possible. 
I deleted the certificates in order to generate new one. But no new ones pop up.

How do i generate new Certificates and connect to the server?

The error message can be ignored as WebIQ Designer tries to retrieve license information from Smart HMI servers, however as ctrlX uses its own licensing this will always fail here. With later versions of WebIQ (2.11) this display has been modified so the error won't be shown.
