Tnt won't work on my server?

You probably setup the tnt cannon incorrectly. Since you didn't explain it very well.. Its a good thing that TNT can blow up the ground, but it didn't push the other tnt away.. Make sure your tnt cannon is correctly made. Look up a youtube tutorial.

 

Im pretty sure this is how you build one http://postimg.org/image/fk5qvd7aj/
