Dock and aircraft shows as disconnected/offline in Cloud API

Hello,
I have successfully deployed the cloud API instance and was able to control the payload by integrating it with the cloud via the DRC. I then attempted the same integration using the Dock, where I was able to log in to the third-party cloud services and successfully bind both devices to the cloud but in the cloud api both the dock and aircraft states as disconnected and offline. I couldn't find any solution could you help me with this. All the firmware is updated and hardware used are DJI pro RC, dock2 and Matric 3TD.  
Below is the
