All of sudden i have getting below issue on new nodes which are part of daemonset installation
Normal BackOff 74s (x554 over 126m) kubelet Back-off pulling image "registry-auth.twistlock.com/tw_u5ko4ug7ddtzhneqzja4fcyf1eekkuxc/twistlock/defender:defender_21_08_529"
Based on the error message, I'd say something is blocking your kubernetes node from being able to pull the image from twistlock.com. I'd first check that the exact image URL that the node is trying to pull actually exists e.g. by doing a manual pull from your own machine. If that works, then check if something might be blocking the new nodes from accessing the URL, e.g. a firewall.
