Error establishing a Redis connection

Replies: 10

Since our host offers an object cache with Redis and WordPress keeps reporting that an object cache would be better, I downloaded the plugin. With the help of the hoster’s support team, I adapted the wp_config.php accordingly.
The dashboard shows that everything is working.

Only when I activate Redis do I get this error message from WordPress.

After I told the hoster’s support, he wrote to me that he could access the cache via the specified port and that the server was running.

What can I do now?

Kind regards,
