cnReach by default communicates to “cloud.cambiumnetworks.com” which is designed to be completely Zero Touch operation and does not require any intervention. However, if the user has changed the URL or any unexpected behavior like device lost connection to cloud account or if you want to verify cloud URL, please follow the below suggestions provided.

- RF Firmware : 1.52.19110 and above
