Mautic Cache Redis config


I am also trying to setup mautic to use Redis so I figured I would use an old post since there is no solution reply.

Your software
My Mautic version is: 4.1.1
My PHP version is: 7.4
My Database type and version is: MariaDB 10.3

Your problem
My problem is:
I am trying to configure Mautic so that it uses Redis instead of filesystem cache. I installed redis-server package on my system as well as php-redis.

These errors are showing in the log:
[no errors detect in logs]

Steps I have tried to fix the problem:

I have tried to looking into documentation here: and I tried to reverse engineer whats happening (I looked into cache bundle). I also consult Symfony docs to see how to configure a dsn.

I came up with the following configuration I put into app/config/local.php:

'cache_adapter' => 'mautic.cache.adapter.redis',
'cache_adapter_redis'     => array(
        'dsn'     => 'redis://<ip>:<port>/<database-index>',
        'options' => array(
                'lazy'           => false,
                'persistent'     => 0,
                'persistent_id'  => null,
                'timeout'        => 30,
                'read_timeout'   => 0,
                'retry_interval' => 0,
'cache_prefix' => 'pa_',
'cache_lifetime' => 3600

But it does not seem to have any effect. When I am using Mautic and regulary inspecting the contents of redis database there is no entries, meanwhile I can see that cache is being generated on the filesystem. What am I doing wrong?

Any help would be much appreciated.
