微信登陆自己的网站，获取accessToken的时候，报java.net.SocketTimeoutException: connect timed out

在本机window上测试没有问题，在服务器linux上就报这个错。
服务器是tomcat6，有nginx。不知道是linux的问题还是nginx的问题。是不是什么地方少配了个什么？
刚开始是报java.net.UnknownHostException: api.weixin.qq.com，在hosts中加了140.207.135.108 api.weixin.qq.com后不报UnknownHostException了，但是一直是java.net.SocketTimeoutException: connect timed out。

没人回答，我自己解决了，是防火墙的问题。 添加如下规则：/sbin/iptables -A INPUT -m state --state ESTABLISHED -j ACCEPT
