Redis is unreachable: Connection refused [tcp://127.0.0.1:6379]

As others before I’m not able to run this plugin on my WordPress website.

I’m using Aruba Linux host and Cloudflare and this is the diagnostic I receive:

Status: Not enabled
Client: 
Drop-in: Not installed
Disabled: No
PhpRedis: 5.3.7
Relay: Not loaded
Predis: 2.1.2
Credis: Not loaded
PHP Version: 8.1.14
Plugin Version: 2.4.4
Redis Version: Unknown

Filesystem: Working
WP_REDIS_PLUGIN_PATH: "/web/htdocs/www.realab.it/home/wp-content/plugins/redis-cache"
Drop-ins: [
    "advanced-cache.php v by "
]

In www.realab.it/home/wp-content/plugins/redis-cache path I find redis-cache.php but no advanced-cache.php file.

Thank you in advance,

Luca
