    Did you configure your connection settings in you wp-config.php?

    Hi Renzo,

    I got by doing the following steps:

    In ElastiCache:

    1) Access the ElastiCache on your dashboard in AWS;
    2) Launch Cache Cluster;
    3) Select Engine Redis;
    4) Specify Cluster Details;
    5) Set Advanced Settings. *Important1: Select the VPC Security Group(s) of your WP instance;
    6) Launch Cache Cluster;

    While ElastiCache will create your Cache Cluster, do the following:

     *Important1: You must have added the same “security group” of this instance WP in your Cache Cluster Redis;

    Now let’s add port 6379 in your security group in EC2:

    1) Access EC2 on your dashboard in AWS;
    2) Select the instance of your WP;
    3) In the tab “Description” click the Security Group of its Instance WP;
    4) Select the tab “Inbound” and edit adding: Custom TCP Rule >> TCP >> 6379 and save;

    Finally, copy and paste the code below into your wp-config and was replacing

    for the endpoint generated in your ElastiCache;

    define ( 'WP_REDIS_HOST', '');
