# SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed

One of the first things you do when creating a new Larvel application is run php artisan migrate to create the application database tables. However you may come across the below message.

```shell
$ php artisan migrate

Illuminate\Database\QueryException

  SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution (SQL: select * from information_schema.tables where table_schema = testsite and table_name = migrations and table_type = 'BASE TABLE')

The cause of this issue is due to a change introduced to the .env.example file. This changed the environment variable DB_HOST from 127.0.0.1 to mysql. The reason for this change is to support [Laravel Sail](https://laravel.com/docs/8.x/sail) which is a Docker development environment for Laravel.

The change means your Laravel application will try and connect to a database server with the hostname of mysql. Unless this exists then the application can't connect.

To resolve the issue just change the value back to 127.0.0.1

```shell
DB_HOST=127.0.0.1
```
