Can not install plugin ! No plugin found!

[niro]

npm install nodebb-plugin-custom-homepage ,and also other plugins.

And then go to the admin panel click "Plugins", nothing show , about 1 minute later, "No plugin found" show there.
From the browser's develop tool, notice that a GET request there, "http://localhost:4567/api/admin/plugins?_=1399982674566" , no respond.

I don't know what's wrong.

@niro Does the NodeBB box have access to the internet?

@julian
Thanks for replied!

1. When click "Plugins" and then timeout, only a "localhost:4567/admin/plugins" URL request, no other internel URL and no error of the browser's develop tool's console.
2. But when refresh the admin panel, two timeout error appear the browser's develop tool's console.
