## Vagrant Authentication Failure Fix
Add config.ssh.insert_key = false in VagrantFile

## APP_KEY error in Laravel
No supported encrypter found. The cipher and / or key length are invalid.

This Error means that App key hasn't been added or it is invalid. To fix it...

php artisan key:generate

Above commad generates a new key. Confirm in .env file that APP_KEY is updated with new key, if not paste the new key here.
