Ansible-Failed to connect to the host via ssh - ssh

Question

I am trying to provison an EC2 instance and to install a LAMP server on it using Ansible from localhost. I have successfully provisioned the instance, but I was not able to install apache,php and mysql due to this error "Failed to connect to the host via ssh.".
OS: El Capitan 10.11.6
Ansible: 2.0.2.0
Here is the playbook: `---
- hosts: localhost
connection: local
gather_facts: no
vars_files:
- "vars/{{ project_name }}.yml"
- "vars/vpc_info.yml"
tasks:
- name: Provision
local_action:
module: ec2
region: "xxxxxx"
vpc_subnet_id: "xxxxxx"
assign_public_ip: yes
key_name: "xxxxxxx"
instance_type: "t2.nano"
image: "xxxxxxxx"
wait: yes
instance_tags:
Name: "LAMP"
class: "test"
environment: "dev"
project: "{{ project_name }}"
az: a
exact_count: 1
count_tag:
Name: "LAMP"
monitoring: yes
register: ec2a
- hosts: lamp
roles:
- lamp_server
The content of the ansible.cfg file:
[defaults]
private_key_file=/Users/nico/.ssh/xxxxx.pem
The inventory:
lamp ansible_ssh_host=<EC2 IP> ansible_user=ubuntu
The command used for running the playbook:
ansible-playbook -i inventory ec2_up.yml -e project_name="lamp_server" -vvvv
Output:
ESTABLISH SSH CONNECTION FOR USER: ubuntu

I have read a lot of threads regarding this error, but nothing helped me. :(
