AX7 VM can not starting

这个问题跟不少人遇到的同样，VM下载，一开始使用正常，特然某个时候，就挂了，直接引用老外的描述吧

When trying to access the Ax I get the following error:

There is a problem with the server

Sorry, the server has encountered an error. It is either not available or it can't respond at this time. Please contact your system administrator.

500 Error

I have done the following:

1. Made sure I have internet connection. (The fact that I am able to provision the user means I have internet connection)

2. By passed the proxy and firewall

3. Ensured the Ax service is running

4. Change the VM's date and time zone to be the same as the host.

试验不少办法，BING，Google一圈，仍是上述连接有网友给出答案。

Have you tried changing the AX7 VM time zone to same as host PC/server time zone?. And make sure the time displayed on the AX7 VM is the correct time. It work like a charm for me.

验证virtulbox 5.0.12有问题，时间同步，只改了时间，时区没有修改，AX的激活服务有问题（猜想）

老老实实，也去修改时区，从新修改时间，问题解决。
