Jaime,
I don't think it's your roles, but here is what I have for the Persona Roles:
You should be ok if you have assigned the ADMIN_ROLE to your user and assigned your user to the system. I do agree with Tamas that you should be using the fully qualified domain name instead of the IP address. I've had some problem with mixing these two. Please let me know if you need any further screenshots.
Thanks,
Todd
