Django新手碰到Errno 10061解决方法

Django新手碰到Errno 10061
在网上看到一个简易微博的源码，想运行一下。地址：
https://github.com/codemage/microblog

我的环境：
win7
python 2.7
Django 1.2.5
apache 2.2
MySQL 5.5
其他需要的库也都安装好了。

把mbproject的内容放到了程序的根目录下，并简单修改了一下settings.py，就能运行了。
刚开始运行也没有问题，注册登录都没问题。但当我post一条微博的时候就会出错。
以下是Windows下的错误信息。之后我用虚拟机在centos下搭建好这个网站，也是在post的时候出现错误errno 111。
上网查，都好像是连接被拒绝之类的错误，但我不知道怎么解决。
哪位高手能指点一下，谢谢！
