Outside listed possible sw defect. I always make sure that traffic is bi-directional. I have had times where gateways would connect to central for monitoring but not get config pushes. I have had other times that microbranch AP's had a power supply issue, by the time they got a new power supply there was an ISP routing issue to the fqdn for central. Also other times that routing breaks for mgmt but routing for vpn tunnel is still find to the vpnc.
I personally always start by validating packets. Its pretty easy to check an edge device for sessions or flows and make sure you are getting packets in response for the fqdn (resolved ip address).

are you asking about the switch firmware?

You can see the current firmware version in the Central dashboard when you click on the device.
Or use the command show version on the CLI

Will,
we are getting these from the New Central then!
I was wondering why you are curious about the firewall type! 😅
I'm looking for the firmware version but no luck. I checked the Documentation Center as well. Any idea?

Where so you seen the alert? Classic or new?
I wasn't asking for the firewall but the firmware on the switch 😊

Will,
we use the hybrid mode (I guess). First, when I log-in the landing page is the new one, and then I can toggle on the Classic one.
We are using PAN as the FW.

I've seen this in the past and believe it was a CX software issue. However, not 100% about this.
Are you seeing this in Classic or New Central? Which FW are you running?

We recently deployed several Aruba 6400 switches as our access layer. Over the past month, we have encountered two separate incidents where Aruba Central reported that all switches had stopped communicating with the platform.
We are trying to determine whether this is a known or common issue with the new version of Aruba Central, or if it may be specific to our environment. Has anyone else experienced similar behavior with 6400 series switches or Aruba Central connectivity?
