Thanks for reaching out.

Could you please confirm, how you configured Hybrid device registration for your environment? Is it with federated domain or managed domain? Also could you confirm device operating system which is having issue?

In case of managed environment, could you verify that AD Connect has synced the computer objects Azure AD. If the computer objects belong to specific organizational units (OUs), configure the OUs to sync in Azure AD Connect. To learn more about how to sync computer objects by using Azure AD Connect, see Organizational unit–based filtering as I see following error from above logs, which indicate device object is not found.

Server ErrorSubCode : error_missing_device  
       Server Operation : DeviceRenew  
         Server Message : The device object by the given id (dcf25f7e-32a2-4353-9c94-55e73da71456) is not found.  
           Https Status : 400  
             Request Id : e3845944-6aad-4a2f-ba45-d92d319699d2

Before you make above changes, please verify if working devices are synchronized and belong to OUs that's part of sync scope in Azure AD connect, because this is not mandatory in case federated domain environment setup.
