Work Perfect with TCP, dont work with UNIX socket!:(

Hi!
I’m installed and configure Redis Server as unix socket. In default settings with TCP work perfect!
If i change setting to use unix socket not work. Other web app work fine with Redis Server as unix socket.
In WordPress i’m installed Redis Object Cache plugin.
My setings is:
wp-config.php
define(‘WP_CACHE’, true);
define(‘WP_REDIS_SCHEME’, ‘unix’);
define(‘WP_REDIS_PATH’, ‘/var/run/redis/redis.sock’);
define(‘WP_REDIS_CLIENT’, ‘pecl’);

In diagnose window:
Status: Not connected
Client: PhpRedis (v3.1.6)
Drop-in: Valid
Ping: +PONG
Redis Extension: 3.1.6
Predis Client: 1.1.1
PHP Version: 7.2.6
Multisite: No
Global Prefix: “wp_”
Blog Prefix: “wp_”
WP_REDIS_CLIENT: “pecl”
WP_REDIS_SCHEME: “unix”
WP_REDIS_PATH: “\/var\/run\/redis\/redis.sock”

Whats wrong in my settings?
Thanks.
