The symptom of the issue will be the AP is online but without any monitoring data.

There are some reasons may cause AP can’t send information to Nebula and could be checked via below items.

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.
