Laravel SQL Connection - Artisan Migrate Works, but Application Can't Connect - php

Question

I'm an irregular Laravel user, and am trying to connect to a remote SQL database.
I've gotten the artisan commands working to create migrations and from the command line I can successfully connect to the database. But, when I try to load the application, the connection fails.
Could not connect to the database. Please check your configuration. error:PDOException: SQLSTATE[HY000] [1045] Access denied for user 'myuser'#'222.222.222.222' (using password: YES) in ... {file location}
What are artisan and the actual app framework doing differently that this connection would respond differently between the 2?
Here is the mysql connection in the database.php file:
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', '123.123.123.123'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'mydb'),
'username' => env('DB_USERNAME', 'myuser'),
'password' => env('DB_PASSWORD', 'mypass'),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '','strict' => true,
'engine' => null,
'sslmode' => 'require',
'options' => array(
PDO::MYSQL_ATTR_SSL_VERIFY_SERVER_CERT => false,
PDO::MYSQL_ATTR_SSL_KEY => 'certs/client-key.pem',
PDO::MYSQL_ATTR_SSL_CERT => 'certs/client-cert.pem',
PDO::MYSQL_ATTR_SSL_CA => 'certs/server-ca.pem',
),
And this is the local environment file:
DB_CONNECTION=mysql
DB_HOST=123.123.123.123
DB_PORT=3306
DB_DATABASE=mydb
DB_USERNAME=myuser
DB_PASSWORD=mypass
I am running the application locally, but the MySQl server is remote.

It turns out that the root cause was that PDO doesn't like the cert generated by Google Cloud SQL.
