CLOUD : Devices Offline

Hi, my APs and Switches appear offline on the cloud. Locally, they can be pinged and their management interfaces can be accessed.
Please see screenshots for specific models:

Dear sir

• Check whether the device serial number is correct which you input on the cloud.
• Check the network connectivity between the cloud and the device. You can login to the device locally to ping the cloud address: ryrcmq.ruijienetworks.com to see whether it can be ping through by using the ping test tool via Diagnostics > Network Tools as the following picture shows:
  

If you can only ping through an IP address, but can not ping through the domain address. Please try to change the device DNS server address to 8.8.8.8 via Advanced > DNS to test again.



If you even can not ping through a public IP address from the device, you may need to check the route through the traffic path to ensure each passing-by device can forward the packets successfully.

• You can also try to configure the cloud service to make it convenient and efficient to manage geographically dispersed networks with diverse device types. Choose One-Device > Config > System > Cloud Service and select the cloud server from the Cloud Server drop-down list, enter the domain name and IP address, and click Save.
  

   
Note: If the server selected is not Other Cloud, the system automatically fills in the domain name and IP address of the cloud server. When Other Cloud is selected, you need to manually configure the domain name and IP address and upload the cloud server certificate.
If the problem still exists, please help show me the ping test result and the cloud service settings on the offline device and please help share with me the network project via the following guide which the devices are in to further check. Thank you for your cooperation:
