KINDLY help on Installing Ansible Automation platform on Single Node

Hi Everyone,

I am trying to install ansible automation platform on rhel 8.5. Unfortunately i am getting ssl connectivity errors when installing it Runningsetup.sh. Could anyone have any idea how to fix it ??? I have generated ssh key and mentioned the path in inventory file before running the setup.
Error Message :

fatal: [host.domain.net]: UNREACHABLE! => {“changed”: false, “msg”: "Failed to connect to the host via ssh:------------------------------------

Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).", “unreachable”: true}

Inventory file details :

ansibleplat.domain.net

#node_type=local

[all:vars]

admin_password=‘xxxxxx’

pg_host=‘’

pg_port=‘5432’

pg_database=‘awx’

pg_username=‘awx’

pg_password=‘xxxxx’

pg_sslmode=‘prefer’

ansible_ssh_private_key_file=“/home/user1/.ssh/id_rsa.pub”

registry_url=‘registry.redhat.io

registry_username='user

registry_password=‘xxxxx’

[automationcontroller:vars]

peers=execution_nodes

ansible_user=xxxxx

ansible_ssh_private_key_file=“/home/user1/.ssh/id_rsa.pub”

Username for Ansible Controle Manager and Remote targets should be same and you have to configure SSH and Set the PubkeyAuthentication should be yes
