The term Cosh[43Pi/Sqrt[2]] has the value 1.5263010243767756 x 10^41, 
and the rest of the expression has a nearly equal but opposite value - 
so evaluated to machine precision the subtraction leaves just noise. If 
you apply FullSimplify it simplifies your expression to something that 
has only one term - so that presumably yields the correct answer.
