Flex Error #2156问题

出现这个问题是因为应用程序使用了特殊端口，修改端口就可以解决。

特殊端口列表

A security change has been made in Adobe Flash Player 9.0.115.0 to block commonly reserved ports (to prevent malicious activity).
If a port number is specified at the end of a URL (such as http://www.adobe.com:80), the port will be checked against a list of commonly reserved ports.
If the port matches the following list, the network request will be rejected and a securityError event will be fired.
The following ports are considered reserved:
