I'm able to ping the instances, but when I run the ansible playbook it's getting failed on the instances

Question

The ad-hoc ansible command runs without any error:

suchetla@xhdlc210320:/scratch$ ansible all -m ping -i /opt/hosts
[WARNING]: Invalid characters were found in group names but not replaced, use -vvvv to see details
xhdlc201168 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": false,
    "ping": "pong"
}
xhdlc201164 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": false,
    "ping": "pong"
}
xhdlc201166 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": false,
    "ping": "pong"
}

But ansible-playbook command fails:

suchetla@xhdlc210320:/scratch$ ansible-playbook -i /opt/hosts mars.yml
[WARNING]: Invalid characters were found in group names but not replaced, use -vvvv to see details
Sudo password:

Below is my playbook.yml:

---
- hosts: xhd-hosts
  become: true
  become_method: sudo
  become_exe: "/tools/xgs/bin/sudo"
  #become_exe: "sudo"
  vars_prompt:
    - name: "ansible_sudo_pass"
      prompt: "Sudo password"
      private: yes
  tasks:
    - name: Install Prometheus Node Exporter
      apt:
        name: device-tree-compiler
        state: present

My inventory is in /opt/hosts:

hostname1
hostname2
hostname3

I created a public key on the ansible installed instance and copied on to the authorized keys on the destination servers.

Based on your logs, your problem is not related to the Network, but to your Filesystem permissions!

This line:

/usr/bin/python3: can't open file '/home/suchetla/.ansible/tmp/ansible-tmp-1711451084.9141061-329683-269580434256761/AnsiballZ_setup.py': [Errno 13] Permission denied

Please check the path and see if there are any specific permission issues, or update your question with ls -alh
