VALIDATION ERRORS

dns apiserver Validation Failed
The dns-controller Kubernetes deployment has not updated the Kubernetes cluster's API DNS entry to the correct IP address. The API DNS IP address is the placeholder address that kops creates: 203.0.113.123. Please wait about 5-10 minutes for a master to start, dns-controller to launch, and DNS to propagate. The protokube container and dns-controller deployment logs may contain more diagnostic information. Etcd and the API DNS entries must be updated for a kops Kubernetes cluster to start.
Validation Failed
Please help in finding the root cause.
1. I tried deleting and recreating multiple time but that did not helped me.
2. Also tried manually placing the master public and private IP to route 53 but it break everything.
As my experience if you have difference in version of kops and kubectl and kubernetes plane version then Kops will never update the Route53 enteries you must need to have the same version for all in my case
[root@ip-20-0-0-66 kuberneteswithkops]# kops version
Version 1.15.0 (git-9992b4055)
[root@ip-20-0-0-66 kuberneteswithkops]# kubectl version
