How can I get mysql to connect with SSL and the devilbox-ca files?

Using Laravel trying to connect with SSL certificate. I’ve coppid the certificate files into the project to ensure it was able to access them ok.

'connections' => [
        'mysql' => [
            'driver' => 'mysql',
            'url' => env('DATABASE_URL'),
            'host' => env('DB_HOST', ''),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
            'password' => env('DB_PASSWORD', ''),
            'unix_socket' => env('DB_SOCKET', ''),
            'charset' => 'utf8mb4',
            'collation' => 'utf8mb4_unicode_ci',
            'prefix' => '',
            'prefix_indexes' => true,
            'strict' => true,
            'engine' => null,
            'options' => [
                PDO::MYSQL_ATTR_SSL_KEY => base_path('ssl/devilbox-ca.key'),
                PDO::MYSQL_ATTR_SSL_CERT => base_path('ssl/devilbox-ca.crt'),
                PDO::MYSQL_ATTR_SSL_CA => base_path('ssl/')

Throws error:
SQLSTATE[HY000] [2006] MySQL server has gone away

Following the guide from here and laravel docs:

~/ssl/devilbox-ca.key or maybe the full path.

These certificate files are only used by the web server. Depending on your configuration of MySQL, it should have its own set of SSL certs (I myself have never configured MySQL with SSL)
