Redis – Connection Refused while Runing Laravel Dusk with Laravel Sail

I’m trying to use Laravel Dusk integrated with Laravel Sail as described in: https://laravel.com/docs/8.x/sail#laravel-dusk

I’m facing some problems when it comes to make this work:

• If a use, a .env.dusk or .env.dusk.local file and run the tests using ‘sail dusk’, I get a CONNECTION REFUSED ERROR (More details below)

• If a use, for example, a .env.testing to setup ENV variables and run ‘sail dusk –env=testing’, the CONNECTION REFUSED ERROR disappear but app continues to use the default .env file while the dusk tests uses the .env.testing, leading to a lot of bugs.

            )

When I run ‘sail dusk’, I get the following error:
