Can't sync time in home network

Go to solution Solved by romans.ivanovs,

Sorry for the delayed reply (you can say I lost track of time).

 

Yes, 123 port is open, but. BUT. I plugged Ethernet cable directly into one of the laptops and it still did not sync! So it's not the router's fault - it's on the Internet provider!

I guess router uses different port (80 I presume) to fetch time.

 

I googled alternative ways to sync time and ended up going with HTP thanks to this post. Works like a charm!

Hi,

 

I have three laptops running Windows 10 1809 connected to the same AP (TP-Link Archer C2 v3 on the latest firmware) over Wi-Fi, none of them can sync time for some reason.

time.nist.gov and time.windows.gov seem dead, so I'm using time.google.com.

AP itself updates time without any problems.

What I have tried:

- Different NTP servers

- Different AP (an older TP-Link)

- Disabling firewall on all laptops and in the AP

- Resetting DNS to the one provided by IPS (I use CloudFlare DNS)
- ping time.google.com - works just fine

- Tinkering with Port Triggering feature of the AP - opening ports 123 UDP and 37 TCP

 

Have I overlooked something? Is there anything else I can try?

 

Thanks!

If you know it has outbound port 123 access, then check the Windows Time service and run

w32tm /resync
