Erroc activation

Hello,

I can’t activate Redis. As soon as I activate it, I get the following error message:

NOAUTH Authentication required.

WordPress is unable to establish a connection to Redis. This means that the connection information in your wp-config.php file are incorrect, or that the Redis server is not reachable.

• Is the correct Redis host and port set?
• Is the Redis server running?

If you need help, please read the installation instructions.

To disable Redis, delete the object-cache.php file in the /wp-content/ directory.

And the site displays the following message to visitors:

Error establishing a Redis connection

To disable Redis, delete the object-cache.php file in the /wp-content/ directory.

Here is the diagnosis:

Can you help me? 

I deliberately concealed the domain name with three dots in the messages. 

Je précise que je suis sous Plesk.
