安装插件disqus提示Unable to connect to the Disqus API servers
disqus是国外非常流行的跨平台评论插件，但安装在wordpress里面的时候显示“Unable to connect to the Disqus API servers”，在官方里面找答案：
This error almost always has to do with a port being blocked by the server. Try contacting them to make sure that they can connect to 'disqus.com' and 'disqus.net' through port 80.
但我们网管已经测试确定服务器是能正常访问disqus.com，这个“disqus.net”因为是死链接所以打不开，但插件依然无法安装，请问哪位大神能指点下？
