在 Homestead 上安装 Flarum 问题

Question

机子上以前就安有, Homestead 的, 下了程序后,
Homestead.yaml 里添加了

 - map: flarum.io
      to: /home/vagrant/Code/flarum

然后只能访问首页, 把虚拟机里的对应的nginx里改成这样, 访问 flarum.io/admin 报

403 Forbidden
You do not have permissions to access this page.

location / {
    try_files $uri $uri/ /index.php?$query_string;
}

location /api {
    try_files $uri $uri/ /api.php?$query_string;
}

location /admin {
    try_files $uri $uri/ /admin.php?$query_string;
}

location /flarum {
    deny all;
    return 404;
}

求怎么解决?
