[users at bb.net] FW: Issue connecting slave to master

[Pierre Tardy]

Hi Colin
Could that be a problem with your slave password?


 def failedToGetPerspective(self, why):
        """The login process failed, most likely because of an authorization
        failure (bad password), but it is also possible that we lost the new
        connection before we managed to send our credentials.
        """
        log.msg("ReconnectingPBClientFactory.failedToGetPerspective")
        if why.check(pb.PBConnectionLost):
            log.msg("we lost the brand-new connection")
            # retrying might help here, let clientConnectionLost decide
            return
        # probably authorization
        self.stopTrying()  # logging in harder won't help
        log.err(why)
