New to Ansible - Facing issue with ping to target host

Ansible Control Machine (ip = 1.1.1.1):

NAME=“Ubuntu”

VERSION=“18.04.3 LTS (Bionic Beaver)”

Target Node (ip = 2.2.2.2):

NAME=“Amazon Linux”

VERSION=“2”

I am able to ssh from Ansible Control Machine to Target node if I manually type the SSH commands (Which means the keys from Ansible Control machine are properly copied to Target node already)

ubuntu@ip-1.1.1.1:~/ansible$ ssh ec2-user@2.2.2.2

Last login: Mon Mar 16 02:13:42 2020 from ip-1.1.1.1.us-west-2.compute.internal

https://aws.amazon.com/amazon-linux-2/

[ec2-user@ip-2.2.2.2 ~]$

But when I run the ansible command to ping target node, I get error:

ubuntu@ip-1.1.1.1:~/ansible$ ansible -i hosts -m ping all -vvv

Please suggest how to resolve the issue.

You're able to connect to "ec2-user@2.2.2.2". The same "REMOTE_USER" must be
specified in Ansible. For example

  $ ansible -i hosts -m ping -vvv -u ec2-user all
