If you read the error message, it says that you have surface mesh with high skewness.
Check where are those surfaces and fix the problems.

in Gambit go to examine Mesh.
Since volume meshing has failed, you can go to examine mesh and choose 2d element.
Then set the lower value to 0.9 for instance, it will display all the 2d elements with skewness over 0.9
Sometimes Gambit mentions which surfaces give you problems (in the error message you got, try to see if gambit mentionned any surface mesh failed or something like this).
