How to Resolve Manually

To resolve this manually, you will need to take a look at the assigned Parameter Group for your Redshift Cluster

According to the AWS Documentation on default values for Parameter Groups, the require_ssl parameter is by default set to false.

You will be able to modify the parmeters using the AWS CLI with the following command:

aws redshift modify-cluster-parameter-group --parameter-group-name your-param-group-name --parameters ParameterName=require_ssl,ParameterValue=true
