Ansible playbook fails on ssh in between the tasks.

Hi!

After 5 out of 11 ansible tasks ran successfuly, my playbook failed throwing the below error:

failed: [<ip>] => {"changed": true, "rc": 1}
stderr: OpenSSH_6.2p2, OpenSSL 1.0.1k-fips 8 Jan 2015

Shared connection to <ip> closed.

I want to know the reason of failure and I am wondering how can ssh fail all of a sudden when it worked for the previous tasks.

Thank You!
