Thank you for your hard work and selfless dedication. I have benefited a lot from this project. But during this period, the program cannot run with the following error:

[NtpChecker] Failed to read NTP clock from the master.System.IO.IOException: Failed to contact host '192.168.1.120'
at Iviz.Ntp.NtpQuery+d__1.MoveNext () [0x00111] in /Users/akzeac/Documents/iviz/iviz_ntp_lib/NtpQuery.cs:44

Looking forward to your reply, thank you。
