If your AP is registered and added in the site on Nebula with offline status, please follow below steps to check the Cloud Control Status for troubleshooting.

 

In the device local Web GUI main dashboard, the Cloud Control Status displays the status of device’s internet and Nebula status. When the AP is online on NCC, three circles are all Green.


          The three circle are Internet, Nebula, Registration, stands for:
          Internet - Internet connection status.
          Nebula - The connection status between the AP and NCC.
          Registration - The AP registration status on NCC.


Firstly, connect a computer under your local network and use a browser to login your device local Web GUI. URL: "http://device IP address"
The ZON utility provides user to scan and check the Zyxel device’s status if you don’t know the device IP address.

Case 1: The AP has never went online on NCC

You’ll see the standalone mode GUI. Please click Standalone Mode then use default credentials (admin/1234) to login.


Nebula Discover must have to be turned ON to enable NCC Discovery. The AP will connect to Nebula Control Center and change to cloud mode management if it is connected to the Internet and has been registered on Nebula.


The table displays the description of each circle status.



If the device can’t connect to Internet or NCC, move the mouse over the circle to check the error message. According to the hint to check your local network settings.



 

Case 2: If the AP is running in cloud mode but went offline on NCC

 

You’ll see the Note with device is managed by Nebula, use credentials (admin/ Nebula site-wide password) to login.

Nebula site-wide password is at Nebula Website Left sidebar >> Site-wide > Configure > General settings > Device configuration > Local credentials > Password

 


 

1.      In the local Web GUI main dashboard, please check the Cloud Control Status.

Nebula Discover always displays ON when device is cloud mode.

If the device can’t connect to Internet or NCC, mouse over the circle to display detailed information and according to the hint to check your local network settings.


The table displays the description of each circle status.



Here are the failed message of Internet and Nebula circles that provides user to rule out the issue in the network settings.

 

Internet failed cases are:

-          Missing default gateway setting

-          Can't get an IP from your DHCP server!

-          Gateway unreachable

-          IP is conflict with (AA:BB:CC:DD:EE:FF), please check!

-          NTP DNS query failed

-          NTP update failed

 

Nebula connection failed cases are:

-          Certificate problem

-          DNS queries failed

-          Proxy authentication failed

-          TCP port 4335 blocked

 

In most cases, it’s the TCP/UDP port being blocked by firewall or ISP. This table is intended to help guide you in creating firewall rules for Nebula, please check your firewall or ISP if they’re blocking them.

We suggest replacing the DNS setting with the static IP address "8.8.8.8" for resolving all domains for Nebula.



If the AP is still offline after above information confirmed or there is no condition as yours list above, please collect Diagnostics at MAINTENANCE page for Zyxel support.
