这对我有用:

php artisan config:clear

即使我更改了 .env 文件中的 config 详细信息，我还是收到了拒绝访问错误.运行上面的命令将清除配置缓存文件，因此 Laravel 将从 .env 文件中读取新数据.

Even though I changed the config details in the .env file, I was getting the Access denied error. Running the above command will clear configuration cache file and hence laravel will read the fresh data from the .env file.
