I have a question about connecting Elasticsearch with Nest.js.

When I make an API call to Elasticsearch, it works fine.

 ![스크린샷 2023-08-20 오전 9.52.49](https://us1.discourse-cdn.com/elastic/original/3X/8/2/8242e9014a977af6dd446bfac2b465d2fccdc025.png)

In Nest.js, I've written the code as follows.

**search.module.ts**

```auto
import { Module } from '@nestjs/common';
import { ElasticsearchModule } from '@nestjs/elasticsearch';
import { SearchService } from './search.service';

@Module({
  imports: [
    ElasticsearchModule.registerAsync({
      useFactory: () => ({
        node: 'http://localhost:9200',
        maxRetries: 10,
        requestTimeout: 60000,
        pingTimeout: 60000,
        sniffOnStart: true,
        auth: {
          username: 'elastic',
          password: 'elastic',
        },
      }),
    }),
  ],
  providers: [SearchService],
  exports: [SearchService],
})
export class SearchModule {}

```

**search.service.ts**

```auto
import { Injectable } from '@nestjs/common';
import { ElasticsearchService } from '@nestjs/elasticsearch';

@Injectable()
export class SearchService {
  constructor(private readonly esService: ElasticsearchService) {}

  async search(q: string) {
    const result = await this.esService.search({
      index: 'csv',
      body: {
        query: {
          match: {
            title: q,
          },
        },
      },
    });

    return result;
  }
}

```

**app.controller.ts**

```auto
import { Controller, Get, Query } from '@nestjs/common';
import { SearchService } from './search/search.service';

@Controller()
export class AppController {
  constructor(private readonly searchService: SearchService) {}

  @Get()
  async getHello(@Query('q') q: string) {
    return await this.searchService.search(q);
  }
}

```

**app.module.ts**

```auto
import { Module } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import { SearchModule } from './search/search.module';

@Module({
  imports: [SearchModule],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}

```

**package.json**

```

However, when I make the API call, I don't receive a response and instead, I get a "Connect Timeout Error." What should I do to fix this issue?

Hi, What kind of error are you receiving in your logs?

Your code is trying to connect to Elasticsearch via `http://localhost:9200`

When you fully deploy and run your Next.js application,  
where is it actually running?

If it is not deployed on the same host running Elasticsearch, then it won't be able to connect to `http://localhost:9200`

When I referred to the practical example from another blog and took a closer look, it seemed there were issues with the index template and the node address part. Now, it's working fine 🙂
