"msg": "SSH Error: data could not be sent to remote host.... Make sure this host can be reached over ssh"

Changed hosts as

[pgsql]
cluster-pgsql-01.local ansible_ssh_host=10.98.0.210 ansible_ssh_user=root
cluster-pgsql-02.local ansible_ssh_host=10.98.0.211 ansible_ssh_user=root
cluster-pgsql-03.local ansible_ssh_host=10.98.0.212 ansible_ssh_user=root

[pgsql:vars]
patroni_scope=cluster-pgsql
patroni_rest_password=flsdjkfasdjhfsd
patroni_postgres_password=flsdjkfasdjhfsd
patroni_replicator_password=flsdjkfasdjhfsd

cluster_virtual_ip="10.98.0.210"

<spoiler title="/etc/ansible/host_vars/pgsql-cluster-01.local/main.yml">
<source lang="yaml">
patroni_node_name: cluster_pgsql_01
keepalived_priority: 99

I set up ssh key and set up authority for root without password on all servers. Removed "ssh.role" from cluster-pgsql.yml :

---
- hosts: pgsql

  pre_tasks:
    - name: Setting system hostname
      hostname: name="{{ ansible_host }}"

    - include: tasks/essentialsoftware.yml
    - include: tasks/open-vm-tools.yml
    - include: tasks/ntpd.yml

  post_tasks:
    - include: tasks/zabbix.yml

  roles:
     - ansible-role-patroni

When I run script "ansible-playbook -u root -k -i hosts cluster-pgsql.yml -b --diff -vvv"
I get error :

*cluster-pgsql-01.local | UNREACHABLE! => {
    "changed": false,
    "msg": "SSH Error: data could not be sent to remote host \"10.98.0.210\". Make sure this host can be reached over ssh",
    "unreachable": true
}

• and for other hosts.

What did I make wrong ?
