I have imported some ansible roles in to foreman and they work but the foreman task still hangs at 25% complete and eventually "fails".

There are 3 machine involved, the foreman server, the smart proxy and the ansible client

It's using Dynflow and everything is on Ubuntu server 16.04
ruby version 2.3.1p122
