Ansible ssh error: mux_client_read_packet: read header failed: Broken pipe Received exit status from master

Question

I have a script /wd/remoteuser/stopALL.sh on remotehost i.e 10.0.0.211 and takes 3 seconds to complete execution and has full permission 775 for remoteuser.

Note: /wd/remoteuser/stopALL.sh does not exist on the host where ansible runs.

I wish to trigger the stop script on remotehost from my ansiblehost.

Below is how i run my ansible playbook.

ansible-playbook /app/playbook/ovs.yml -i /app/playbook/ovs.hosts -t stop -f 5 -e Environment=PROD -e Country=SRILANKA -vvvv

cat /app/playbook/ovs.yml

---
- name: Play 1- check for login and mount point
  hosts: "*{{ Country }}_{{ Environment }}"
  user: "{{ USER }}"
  any_errors_fatal: true
  vars:
    ansible_ssh_extra_args: -o StrictHostKeyChecking=no -o ConnectTimeout=90 -o ServerAliveInterval=50
    ansible_ssh_private_key_file: /app/ssh_keys/id_rsa
  gather_facts: false

  tasks:

    - name: Execute backup stop1 script
      tags: stop,restart
      script: "{{ stopscript }}"
      args:
        chdir: "{{ stopscript | dirname }}"
      register: stopscriptoutput


    - name: Debug stopscript
      tags: stop,restart
      debug:
        msg: "{{ stopscriptoutput.stdout }}"

cat /app/playbook/ovs.hosts

[APP_SRILANKA_PROD]
10.0.0.211 USER=remoteuser stopscript=/wd/remoteuser/stopALL.sh countrydet=SRILANKA evt=PROD

Output:

I get this ssh read header failed: Broken pipe error even if I use the shell module as shown below.

- name: Execute backup stop1 script
  tags: stop
  shell: "sleep 90; {{ stopscript }}; sleep 90"
  register: stopscriptoutput

Kindly suggest how can I resolve the ssh broken pipe error and get the script to execute remotely?
