How do I turn on TLS for an existing self-managed ElastiCache cluster?

Resolution

Note: If you receive errors when you run AWS Command Line Interface (AWS CLI) commands, then see Troubleshooting errors for the AWS CLI. Also, make sure that you're using the most recent AWS CLI version.

To turn on in-transit encryption for your cluster, make sure that your cluster meets in-transit encryption conditions for Amazon ElastiCache for Valkey and Redis OSS. Then, turn on in-transit encryption for your cluster.
