Laravel 5.5 Scout + Elasticsearch "No alive nodes found in your cluster" error?

Question

elasticsearch

Installed laravel-scout-elastic package .
Everything according to the instructions.

// config/app.php
'providers' => [
    Laravel\Scout\ScoutServiceProvider::class,
    ScoutEngines\Elasticsearch\ElasticsearchProvider::class,
],

// config/scout.php

    'driver' => env('SCOUT_DRIVER', 'elasticsearch'),

    'elasticsearch' => [
        'index' => env('ELASTICSEARCH_INDEX', 'laravel'),
        'hosts' => [
            env('ELASTICSEARCH_HOST', 'http://localhost'),
        ],
    ],

In the model:

// App\Theme
namespace App;

use Illuminate\Database\Eloquent\Model;
use Laravel\Scout\Searchable;

class Theme extends Model
{
    use Searchable;
}

Import to search indexes:
php artisan scout:import "App\Theme"
throws an error

In StaticNoPingConnectionPool.php line 51:
  No alive nodes found in your cluster

When creating a new entry, the same error:

Elasticsearch \ Common \ Exceptions \ NoNodesAvailableException
No alive nodes found in your cluster

I've looked all over and there's nothing about it anywhere

Answer 1

Check access to Elastica from another program, for example, from a console utility.
If you have access, then your connection settings in your application are not correct.
If there is no access - well, you understand.

Answer 2

env('ELASTICSEARCH_HOST', 'http://localhost:9200'),

Not?
And check if elastic is running. Can be done with curl
