@override
(bool, DisconnectReason?) interceptUpgraded(Conn conn) {

    _logger.fine('Blocked upgraded connection: ${conn.remotePeer}');
    return (
      false,
      DisconnectReason(
        code: 1,
        message: 'Peer is blocked',
      ),
    );
  }
  if (isConnBlocked(conn.id)) {
    _logger.fine('Blocked upgraded connection: ${conn.id}');
    return (
      false,
      DisconnectReason(
        code: 2,
        message: 'Connection is blocked',
      ),
    );
  }
  return (true, null);
