I changed the way to specifiy the cell, erasing the CELL_PARAMETERS block.

   ibrav = 14,
   celldm(1) = 56.7 ,
   celldm(2) = 1.0 ,
   celldm(3) = 1.0 ,
   celldm(4) = 0.0 ,
   celldm(5) = 0.0 ,
   celldm(6) = 0.0 ,

It solved the problem.

Thank you for your advice.

the algorithm that estimates the number of neighbors for DFT-D implicitly 
assumes that the lattice constant is the lattice constant, not a bogus number 
like the above one. Try first of all to set a proper value for "celldm".
