NTP Update Failed

kevindd992002

I have two sites connected to one NCC. One site has 9 NWA210AX AP's and another has only 1 NWA210AX AP. I'm checking the event logs on both sites and I get a lot of "NTP Update Failed" entries there even though I don't see any time issues. How can I troubleshoot this?

Hi @kevindd992002

We've noticed that your Nebula site is located in the Philippines, and we've encountered similar issues reported by other users in the Philippines. It appears that some ISPs in the region are blocking access to Nebula Control Center's relied-upon NTP server, *.pool.ntp.org.

To address this, here are three possible solutions:

1. Contact your ISP and request them to unblock access to the FQDNs: 0.pool.ntp.org and 1.pool.ntp.org.
2. Adjust your firewall/router DNS settings to replace the FQDN 0.pool.ntp.org and 1.pool.ntp.org with Google's NTP address (for example: 219.239.35.8).

Additionally, we're currently working on adjusting the NTP server domain in our next firmware release to improve user experience. Stay tuned to the https://community.zyxel.com/en/categories/wlan-news-and-release for updates on the latest firmware release.

If you need further assistance, please feel free to reach out to us.

I see. I guess I just need to wait for the latest firmware release then. Do you know why I still get the correct time in the logs and all of Nebula center if NTP updating is failing on all my AP's?

Hi @kevindd992002

Even though the NTP updates are failing intermittently on your APs, they still manage to synchronize time occasionally. As a result, the time on your devices remains relatively close to the time on the Nebula CC. Consequently, the logs reflect the correct time.

Hi Kay. Ok, I understand. Is there an ETA to the firmware fix?

The release of the next firmware is scheduled for 2024/Q3. Stay tuned to the WirelessLAN New Release for the latest firmware updates.
