注意事项

按要求需要修改hosts文件，但今天（2019-05-30）尝试激活时IDEA提示：

your activation code could not be validated error 1653219

解决办法

1. 去除hosts文件中添加的jetbrains相关的配置项

0.0.0.0 account.jetbrains.com
0.0.0.0 www.jetbrains.com

1. hosts文件中增加配置

0.0.0.0 https://account.jetbrains.com:443

1. 刷新dns
   Windows cmd中执行

ipconfig /flushdns

hosts文件路径
