Why am I seeing "device not found" AirPort Admin?

I have an AirPort extreme and my parents have a TimeCapsule. They're both displaying the "device not found" message in AirPort Admin. We've tried cycling the power etc. Our networks still operate, however we can't connect to manage them and my parent's backups have ceased. Is anyone else seeing this?

Well, turning off BTMM doesn't help managing remote Airport basestations, especially when Manage over WAN is not turned on (as per good security practice). Using BTMM to a remote OS X system works to access a remote Airport basestation if, and only if, there happens to be a remote OS X system to connect to and run Airport Utility.


This problem occurs with Airport Utility 6.3.6 and 6.3.7 on 10.11.6 and 10.12.x and with Airport firmware 7.6.4, 7.7.3, and 7.7.7. Additional symptoms include disappearance of printers shared using an Airport Extreme.


However, screen sharing access to remote OS X systems remains viable. I have tested using Airport Utility on systems accessed through Screen Sharing and found identical symptoms.


My conjecture, based on geographically diverse systems and software versions is that there has been some change in apples wide area bonjour service which is not successfully communicating with the Airport basestations. This would mean that Apple is the direct source of the problem, not any user boxes.

I also found that if you unplug the power cable from the AE and then plug it back in that it will show up again temporarily in Airport Utility on my iMac allowing access to the edit functions from there. Just hit the edit button quickly once the AE re-appears because after about 30 seconds to a minute it will become unaccessible again and show up like the screenshot that Brian added above.
