Trying to complete our onboarding bench. I have the SMs communicating outbound via the ethernet port, but Maestro status is “Waiting for AP session establishment”
We have the credentials manually added. Is it going to be the case that the 450 can only be onboarded via the wireless interface even with eth port internet access?
We have a testing AP that can do this but it would be more efficient to do it via the ethernet port

It shouldn’t really matter, but is the cnMaestro on-prem or in cloud? We have on-prem we reach via the ethernet interface.

Cloud. It’s not even looking for it, its waiting for rf interface
