 * Hello
 * I installed Rublon and activated it on my WordPress Website.
    When I try to activate
   authentification via Rublon, after scanning the code and answering the question,
   the web page replys with a
 * Rublon error code: CR_RUBLON_EXCEPTION_CODE_CONNECTION_ERROR
 * What can I do?
    Thank you.

 * Hi voala
 * Thank you very much for your interest in Rublon.
 * It looks like there was a connection problem during plugin registration. Your
   server might be blocking outgoing cURL connections. Another possibility is that
   there was a timeout. Please check if your firewall or something else might be
   blocking those connections.
 * Is your WordPress website being hosted by a shared hosting provider or on a dedicated
   server?
