Can you connect with any other products (phpMyAdmin locally, heidisql, etc) ?

Without knowing anything about RDS by gut feeling would be an IP restriction, but it's hard to tell without the error message.

If your MySQL database is on a remote server it may well be one of the following issues:

• Firewall Block, the server with the MySQL service may be behind a firewall that is set to block eternal access to the port that MySQL operates on
• MySQL User Permissions, if the MySQL service is not sat behind a firewall then the next cause may be that the user has only localhost access permissions

My hosting provider requires that I log into the control panel and whitelist the IP my machine is on before I can connect to it.

Hello have you run php artisan migrate? and was table migrated to remote db? If yes then please guide me. I dont know how to migrate on remote.

Thank you.
