i'm trying to add a chef client node from chef workstation using knife bootstrap command.But getting error message as '''ERROR: Train::Transports::SSHFailed: SSH session could not be established'''

I have disabled iptables on chef client

[[email protected] ~]# service iptables status
Redirecting to /bin/systemctl status iptables.service
iptables.service - IPv4 firewall with iptables
Loaded: loaded (/usr/lib/systemd/system/iptables.service; disabled)
Active: inactive (dead)

Jul 29 16:21:18 chefclient.jp.com systemd[1]: [/usr/lib/systemd/system/iptables.service:5] Unknown lvalue 'AssertPathExists' in... 'Unit'
Hint: Some lines were ellipsized, use -l to show in full

'''knife bootstrap 192.168.56.6 -N chefclient.jp.com -U root --sudo -i /root/Downloads/chefsetup.pem'''

Getting result as:
