Laravel env('APP_URL') is not returning the correct value for localhost

When trying to retrieve the APP_URL from the Laravel config it returns the wrong URL for development only.

My env file has the following:

APP_URL=http://127.0.0.1:9000

However when I call env('APP_URL') it returns me:

'http://localhost'

Which will not work with my current docker set-up it has to be 127.0.0.1:9000

In my config/app.php file I have the following:

'url' => env('APP_URL')

I have tried php artisan config:cache and php artisan config:clear but I still get the same result of http://localhost

Any ideas on where it could be getting http://localhost from other than the .env or config/app.php?
