Ansible ssh error - Make sure this host can be reached over ssh: Connection timed out during banner exchange

[Mohtashim S]

Below is the command to run Ansible Playbook:

ANSIBLE_SCP_IF_SSH=y ansible-playbook -v -i /web/aes/admin/playbooks/PB_BAU/ccc_vel.hosts /web/aes/admin/playbooks/PB_BAU/cccvel_restart.yml -e ENV=$SH_ENV -e ACTION=$SH_ACTION --tags $3 -e instance_name=$Instance

Here is the playbook code:

- hosts: "{{ENV}}_*"

  user: "{{USER}}"

  gather_facts: yes

  pre_tasks:

       - name: Check if all hosts are reachable

         fail:

           msg: >

             [REQUIRED] ALL hosts to be reachable, so flagging {{ inventory_hostname }} as failed,

              because host {{ item }} has no facts, meaning it is UNREACHABLE.

         when: hostvars[item].ansible_facts is not defined

         with_items: "{{ ansible_play_hosts }}"

         run_once: true

         tags: checkserver

       - debug:

           msg: "This message means all hosts are reachable"

         tags: checkserver

  tasks:

       - name: "Ping {{ENV}} vel Servers"

         ping:

  roles:

    - { role: BL, when: USER == 'dias' and 'Business' in instance_name }

I'm using Ansible version 2.10

As you can see despite the error the role's task seems to have triggered and the services tried to start.

Can you please suggest the exact fix for this issue please?

[zil...@gmail.com]

Can you ssh to the host with the creds you're providing Ansible?

[Mohtashim S]

Yes, I also mentioned that the ansible command module also gets triggered on remote host. I m just concerned about the error message as it fails the playbook.

[Mohtashim S]

Why no updates on this issue. Can someone please check.
