Following firmware update, "disconnected" Airmax AC devices are "active" again in UNMS

Following the upgrade to UNMS 0.9.0, all Airmax AC devices on v8.3.1-beta or v8.3.1-RC have been showing as disconnected.

 

Following upgrades to airOS v8.3.2-Beta they are all working again and updating in UNMS 0.9.0 as expected.

@cettinger Hi Carl, thank you for reporting it and it's very helpfull that you sent me a PM with your logs.

> 2017-07-28 23:30:15 ERROR failed to decode message from UNMS

 

It's a problem with AES key. There is a detailed description how to fix this issue on this wiki page. We would like to identify all scenarious which can lead to this issue so let me know if you have this problem again. Thank you.

Device log:

UNMS log:

 

2017-07-29T02:34:34Z unms {"container_name":"/unms","source":"stdout","log":"170729/023434.407, [log,error,ws] data: WS - disconnection, unexpected data: TypeError: Cannot read property 'connection' of undefined)","container_id":"XXX"}

 

If I understand it correctly this issue was fixed in your UNMS by upgrade from v8.3.1-beta/v8.3.1-RC to airOS v8.3.2-Beta. UNMS terminated connection with airMAX devices because there was a problem with initial data from airMAX. We can replicate it with v8.3.1-RC and we will fix it.
