Laravel: error "The page has expired due to inactivity" (419 unknown status)

I get the error The page has expired due to inactivity. Please refresh and try again. on a Laravel 5.6.39. In Chrome Network tab it says error login - 419 unknown status

I can reproduce the error following these steps:

• go to login view
• enter username and password and don't check "remember me" flag
• wait that session expires (for test purpose I set SESSION_LIFETIME to 1 minute)
• hit Login button and I get that error

I already read and tried the most common causes:

• @csrf is present in the login form (it's the default authentication by Laravel)
• the folder storage has 755
• tried to launch php artisan cache:clear php artisan config:clear php artisan route:clear php artisan view:clear php artisan config:cache php artisan key:generate
• I'm using the default SESSION_DRIVER=file but in production I also tried to replace it with SESSION_DRIVER=cookie with SESSION_DOMAIN=https://app.my-domain.com/

My .env file

APP_NAME='My App Name'
APP_ENV=local
APP_KEY=base64:+P6N350yBjAzw4q3oarQY/8mpJxDY7uwTTafriWrvMM=
