almond+ connection lost

[medatom]

I am on R066. For the past week, occasionally when I try to access the hub through the android app, it says almond+ is offline. But I can access the internet with our any issues.
If I want to reconnect to the hub, only way is to turn the phone WiFi off and on again. This happens from different phones as well so I know it's not the phone setting.
The interesting thing is while getting message that almond+ is offline, the lan or Wi-Fi connection is still running good.

I'm having exactly the same problem, although turning off/on the wifi does not solve the problem. 
It just says the Almond is offline, through the app and also connect.securifi.com

I had this issue and had to use the Wizard on the router to unlink it and then add it back. The app now shows the router and is able to fetch info again.
