iodine fails its ping test

I'm trying to get iodine working on my Ubuntu machine.

The server is working fine, but when it try to establish a connection, and change the route table using the default iodine-client-start script i get the following output

Everything looks find, the connection works, but then I tried to change the route table and the connection breaks. Any idea how to fix it?
