Onboarding E410 AP to cnMaestro onPremise

Products cnMaestro
1

Hi! I am relatively new in Cambium Networks, so forgive me if I ask stupid questions.
I am trying to onboard E410 AP to cnMaestro3 on Premise, but I am having problems connecting.

I have cnPilot e410 AP (latest firmware) on 192.168.100.0/24 network, and cnMaestro 3(latest version) on premise server on 192.168.200.10/24 network.
AP can ping the server and vice versa, but can’t connect to cnMaestro server.
This is what i get in logs:

Any help is appreciated.

Welcome to the Cambium community!

It’s probably not relevant, but there appears to be an extra space before the IP address on those log lines. Can you find where that space is being introduced and remove it, and see if that makes a difference?

If you visit https://192.168.200.10 in a web browser while on that same network, do you see cnMaestro?

I think this is just bad formatting, there is no space when i check logs on AP.

Yes, when I open https://192.168.200.10 I see cnMaestro, no matter what network I am on (.200 or .100).
Ofcourse, since I don’t have https certificates I do get “Your connection is not private” error before I can login, but everything works ok after i bypass it.
I tried with both enabled and disabled “Validate Server Certificate” option, but cnMaestro Connection Status keeps showing cnMaestro Connection Status “Connecting to 192.168.250.160 in 5 minutes…”

Da li je url cnmaestra na APu unesen rucno ili preko dhcpa? Probaj unjeti rucno mac adresu na cnmaestro i kliknuti “approve” pa pricekati koju minutu

I am gonna answer in english just so someone else can use this so fix same problem…
cnMaestro URL is inserted manually in URL field, not using DHCP.
I did try to enter MAC address in cnMaestro, bul all i get is Status: Waiting for Device

I think these log lines mean that the device is successfully contacting the cnMaestro front-end web server, but the front end is failing to pass the request to the appropriate back-end handler. This may mean that the request is malformed, or that cnMaestro is misconfigured somehow.

You should raise a support ticket so that someone who knows what they are talking about (not me) can help you.
