Hi,

I want to create a custom python sensor and register it at my prelude manager. The sensor and manager are running on different machines. Everytime I try to register, I get the error message of a failed TLS handshake.
I even tried to run and register your python example at https://www.prelude-siem.org/projects/prelude/wiki/DevelAgentBuilding on the same machine as the manager, but I got the same error:

root@debian770:~# prelude-manager

root@debian770:~# prelude-admin register "MySensor" "idmef:w" 172.16.15.116:5553 --uid 1000 --gid 1000

You now need to start "prelude-admin" registration-server on 172.16.15.116:5553:
example: "prelude-admin registration-server prelude-manager" 

Enter the one-shot password provided on 172.16.15.116:5553:
Confirm the one-shot password provided on 172.16.15.116:5553:

Connecting to registration server (172.16.15.116:5553)...

GnuTLS handshake failed: Handshake failed.

Do you have any idea how to solve this?
