Redis logs:

redis         | 1:M 28 Mar 2021 17:09:58.588 - Client closed connection

PHP logs:

php           | NOTICE: PHP message: RedisException: Connection refused in /var/www/html/wp-content/object-cache.php:578

php           | #8 {main}

Seems to be a problem of the plugin, because I can connect from php cli without problems (and authenticate too)

RESOLVED: wp config constants should be defined before loading other files
