How can I add Hong Kong ntp server into other country zone which have large population but few ntp server

The NTP monitoring system near New York City is unable to contact the NTP server via NTP or even ping. I don’t know where the problem is.

I then change my IP and tried to test the ntp server again, but it still says’cannot check ntp status’. My ip now is 119.236.127.206

alica@atelier:~$ sntp 119.236.127.206

Now your computer is online, but my SNTP client cannot connect to it. As I said before, did you test the Windows built-in time synchronization against time.windows.com? You should first make sure if your new ISP is blocking NTP packets before we can move on.
