Hi, I think you have to make this line HIS NE2 1 ZIH ZN 1 0.25 HISZ ZIH as HIS NE2 1 ZIH ZN 3 0.25 HISZ ZIH
because zinc needs to make 3 special bonds. Also check NE2-Zn distances are all within 10% of 0.25 (Assuming you've already defined HISZ and ZIHS in .rtp file.) You also might want to try pdb2gmx without -his option after above modifications.
