I'm dealing with an issue onboarding a cnMatrix switch (EX 2010-P) running 2.0.4-r1 software version (already tried on 2.0.5-r2 version) on on-premises cnMaestro running 2.2.0-r60 OVA version.
Despite i set my local cnMaestro ip address (which is reacheable via ping) to cnMatrix as :
Have you installed a certificate in your cnMaestro On-Premises installation? Certificate validation is usually disabled on devices by default for On-Premises. Can the switch connect when validation is disabled?
This issue was solved by disabling Cambium ID based authentication in the On-Premises settings. It is disabled by default but if enabled could cause devices to rejected without an onboarding key set.
