大概一两个月前，mac上的V2瑞突然连不上了。但因为是在家里用，路由器上有设置，所以也无所谓。但这两天出来了，很不方便，就动手查找原因。

但是呢，除了mac，两个手机上都没有问题的。查找了半天，都没有很好的答案。依次试了以下方案。
新服务器
升级V2瑞X的V2瑞 core
都不管用。直到看到了这一条：https://github.com/v2ray/v2ray-core/issues/1154。他写道“I fixed it by synchronised the client time and server time”翻译出来就是“我通过同步客户端时间和服务器时间来修复它”
一拍脑袋，对呀，我mac确实不知道什么原因时间快了3分钟。一查看，发现自动同步的打勾没有选。一琢磨，好像是哪一次突发奇想，自己把表调整快几分钟，让自己更准时
设为自动获取时间后，V2Ray立即工作了。

成功了，非常感谢！！！
原来是系统时间问题，人懵了快。
牛逼666啊，疑难杂症了属于是
