Laravel 5.2 Database [xxx]未配置，同时在database.php中定义

So I have 3 mysql DB's defined in my database.php file. I had 2 for the longest time and everything worked fine. I have one titled mysql, one mysql1 and one mysql2. The first 2 work fine, I copied the second one, changed the name to mysql2 and added the proper parameters but it still always says "Database mysql1 not configured. Is there some sort of cache? or somewhere else I have to define it? I am calling the DB through a model like this.

protected $connection = 'mysql1';

This is my database.php for clarification

'mysql' => [
    'driver'    => 'mysql',
    'host'      => 'localhost',
    'database'  => '',
    'username'  => '',
    'password'  => '',
    'charset'   => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix'    => '',
],
'mysql1' => [
    'driver'    => 'mysql',
    'host'      => 'localhost',
    'database'  => '',
    'username'  => '',
    'password'  => '',
    'charset'   => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix'    => '',
],
'mysql2' => [
    'driver' => 'mysql',
    'host' => 'localhost',
    'port' => '3306',
    'database' => '',
    'username' => '',
    'password' => '',
    'charset' => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix' => '',
    'strict' => false,
    'engine' => null,
],

This was fixed by using the command

php artisan config:cache

I submitted a Laravel issue request to fix it since that absolutely should not be required to change the DB connections variable.
