Is it cloud or on-premises cnMaestro? I am using cloud cnMaestro
Is your PMP450AP opeartional and able to ping out to the server with the appropriate cnMaestro address? I am able to reach the internet and cnMaestro from the AP's.
The one thing I have noticed is that we are using the CBRS functinoality and that is giving us issues with moving between the AP's.
