Resolving the primary server connection issue

NetBackup operator pod logs displays the following error:

Failed to connect the Primary server. "error":

"Get \"https://abc.xyz.com:*/netbackup/security/cacert\":

dial tcp: i/o timeout

The above error appears due to the following reasons:

Operator, primary server and media server pod must have been started in different availability zones.
Load balancer IP address and node on which primary server pod have started are in different availability zones.
Load balancer created for NetBackup load balancer service is in failed state.
FQDN to IP address given in networkLoadBalancer section in CR spec is not DNS resolvable.

To resolve the primary server connection issue, perform the following

Delete the primary server and media server CR instance using the following command:
kubectl delete -f <environment.yaml>
Caution:
Be cautious while performing this step.
Fix the issue and provide appropriate details in CR specs in environment.yaml file.
Redeploy the NetBackup by reapplying the environment.yaml file using the following command:
kubectl apply -f environment.yaml
