 * It seems like your WordPress installation is unable to connect to your Redis 
   Server.
 * Make sure it’s running 👍

 * It works, just where do these errors come from and how do you eliminate them?

 * This is something your hosting provider or web developer can assist you with,
   since it’s related to Redis Server and not this plugin.
 * The error is coming from WordPress trying to connect to Redis, but Redis isn’t
   responding. I don’t know how to eliminate it in your particular case.
