Activation of ROC crashes website

Hi,

I installed Object Redis Cache on our website.
Plugin says :
État : Non activé (Status : not activated)
Système de fichiers : Accessible en écriture (Filesystem : Writable)
Redis : Joignable (Redis : reachable)

But when activating the website crashes immediately :
Error establishing a Redis connection
read error on connection to 127.0.0.1:6379

I tried to clear cache in CLI but it doesn’t solve the issue.
WP : 6.8.3, PHP 8.2 (php8.2-redis installed),

Any idea ?

TIA
