Redis Object Cache Encryption

Replies: 2

I’m configuring ElastiCache for Redis to work with my RDS instance and have enabled both encryption-at-rest and encryption-in-transit.

However, when I set transit encryption mode to “Required”, my WordPress plugin Redis Object Cache fails to connect to the ElastiCache cluster. I want to enforce encrypted TCP connections but still maintain plugin functionality.

Could you help identify whether this issue lies with the ElastiCache configuration or the plugin’s compatibility with the required encryption? Any guidance on how to resolve this would be appreciated.
