AX7 VM can not starting

這個問題跟不少人遇到的同樣，VM下載，一開始使用正常，特然某個時候，就掛了，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.

試驗不少辦法，BING，Google一圈，仍是上述連接有網友給出答案。

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.

驗證virtulbox 5.0.12有問題，時間同步，只改了時間，時區沒有修改，AX的激活服務有問題（猜想）

老老實實，也去修改時區，從新修改時間，問題解決。
