Ansible hangs on git clone

I am trying to setup a task that clones a repo in a vagrant box. I have setup agent forwarding properly, added the repo server in ~/.ssh/known_hosts, and have validated I can log in as vagrant user and clone the repo without being asked for credentials and host key is not checked ( git clone runs without a hitch ).

My task is set up as follows:

- name: Check out pname dev branch
  git: repo=ssh://[email protected]:dev-team/pname.git
    dest=/home/vagrant/pname
    version=dev
    accept_hostkey=yes
  become: yes
  become_user: vagrant

My task just hangs, verbose set to -vvvv gives the following output:

Is there a way to figure out what is holding up the git clone task?

Update:

Running the following task works as expected:

- name: Clone project dev branch
  shell: git clone [email protected]:dev-team/project.git /home/vagrant/www/project
  sudo: false
  args:
 creates: /home/vagrant/www/project

While the following, using git native task handler fails (does not hang anymore):

# This task does not work!
- name: Check out project dev branch
  git: repo=ssh://[email protected]:dev-team/project.git
       dest=/home/vagrant/www/project
       accept_hostkey=yes
       force=yes
  sudo: false

This is the error that is shown:

failed: [default] => {"cmd": "/usr/bin/git ls-remote 'ssh:********@gitlab.cgi-web.ca:dev-team/project.git' -h refs/heads/HEAD", "failed": true, "rc": 128}
stderr: GitLab: The project you were looking for could not be found.
fatal: Could not read from remote repository.

Why would the shell task work, versus the native git task?
