 * Hi!
 * The plugin shows a connection refused, when i copy the connection code to a simple
   PHP file, the file can connect to redis…
 *     ```
       Status: Niet verbonden
       Client: PhpRedis (v5.3.2)
       Drop-in: Valid
       Disabled: No
       Ping: 
       Errors: [
           "Connection refused"
       ]
       PhpRedis: 5.3.2
       ```
   
 * Code copied from plugin to separate file which successfully connects:
 *     ```
       connect_using_phpredis($parameters);
        function connect_using_phpredis( $parameters ) {
          $version = phpversion( 'redis' );
          $redis = null;
   
              $redis = new Redis();
   
              $args = [
                  'host' => $parameters['host'],
                  'port' => $parameters['port'],
                  'timeout' => $parameters['timeout'],
                  '',
                  'retry_interval' => (int) $parameters['retry_interval'],
              ];
   
              if ( strcasecmp( 'tls', $parameters['scheme'] ) === 0 ) {
                  $args['host'] = sprintf(
                      '%s://%s',
                      $parameters['scheme'],
                      str_replace( 'tls://', '', $parameters['host'] )
                  );
              }
   
              if ( strcasecmp( 'unix', $parameters['scheme'] ) === 0 ) {
                  $args['host'] = $parameters['path'];
                  $args['port'] = -1;
              }
   
              if ( version_compare( $version, '3.1.3', '>=' ) ) {
                  $args['read_timeout'] = $parameters['read_timeout'];
              }
   
              call_user_func_array( [ $redis, 'connect' ], array_values( $args ) );
   
              if ( isset( $parameters['password'] ) ) {
                  $args['password'] = $parameters['password'];
                  $redis->auth( $parameters['password'] );
              }
   
              if ( isset( $parameters['database'] ) ) {
                  if ( ctype_digit( (string) $parameters['database'] ) ) {
                      $parameters['database'] = (int) $parameters['database'];
                  }
   
                  $args['database'] = $parameters['database'];
   
                  if ( $parameters['database'] ) {
                      $redis->select( $parameters['database'] );
                  }
              }
   
   
              var_dump($redis->ping('test'));
       }
       ```
   
 * `string(4) "test"`

 * Odd. Can you move the `WP_REDIS_*` constant to the very top of your `wp-config.
   php`?
