I realize this is a late post, but we recently ran into a similar problem and it occurred after a maintenance update to the cloud platform. What we found was that the front-end servers were relocated to an IP address which (according to our GeoIP filters on the firewall) is based in Germany. We were blocking Germany, and therefore the devices would not show in the cloud. One of those things you don't always think of, especially when it occurs on a device for which you don't "see" where it's going from a contextual sense.

Hi, After getting console access to AP I noticed that it could communicate to devices.extremecloud.com using ip but not with dns name. AP was configured to use dhcp for WAN access but for some reason it had locked resolver setting in resolv.conf which had wrong resolver ip set. I did cset factory reset which fixed the problem. Now ezcloud sees AP as it should.
I can see on fw logs that ap communicates to devices.extremecloud.com using port 443 (ssl app) as you adviced.
Thx.
Br,

Hi Mikael,
you might find the GTAC Knowledge article How does my Access Point communicate to the ExtremeCloud? useful.
