Redis do not connect via plugin even if it connects via terminal

Hi there,

I am trying to test out object cache with Redis. I have set up a server from redislabs.com, and I successfully connected to it via terminal on my computer. Having passed all the required information on the wp-config file, I still can’t get connected via WordPress. Here is the diagnostics:

As well as bellow you can find the part of my wp-config file:

define( 'WP_CACHE_KEY_SALT', 'lekitable' ); 
define( 'WP_REDIS_SCHEME', 'tls' );
define( 'WP_REDIS_HOST', 'redis-18269.c300.eu-central-1-1.ec2.cloud.redislabs.com' );
define( 'WP_REDIS_PORT', REDACTED_FOR_PRIVACY );
define('WP_REDIS_PASSWORD', ['default','REDACTED_FOR_PRIVACY']);

Do you have any idea why is this happening ? Please note that all of these details are mentioned on top of the wp-config
