在服务器上部署后，Laravel 5.8电子邮件验证链接或APP_URL将返回localhost

Question

I've configure everything in .env & config/app.php in my Laravel 5.8 for production preparation in heroku like this :

APP_NAME=Laraclass
APP_ENV=production
APP_KEY=xxx
APP_DEBUG=true
APP_URL=http://larafresh.herokuapp.com

And then I try to create an account and check my email verification feature, and the verification link or APP_URL inside the email returns to http://localhost:8000, I've tried to restart my app, and clear the config but still stuck at here. I don't know what happen here, because on another link that I've created (outside of email function), it returns to APP_URL that I've set.

Answer 1

First clear caching of config.

php artisan config:clear

Then restart app.

php artisan serve
