NTP sync failure can affect your AP’s ability to display connected clients or maintain proper functionality on Nebula. This happens because Nebula is time-sensitive with logs and services. Many AP features, like client connection logs, schedule SSID, maintenance, rely on accurate time synchronization.

To resolve the issue, ensure below settings are correct.

Firewall Rules: Make sure that the firewall rules on your network allow the APs to communicate with Nebula's servers. Verify that the necessary ports (UDP ports 123 and TCP ports 80, 443, 4335, 6667) are open for outbound traffic from the APs.

Ensure DNS Settings: Ensure that the DNS server can resolve NTP server (Network Time Protocol: *.pool.ntp.org)or set it to a public one (8.8.8.8) to prevent time synchronization issues.
