I was posting back on March 2nd regarding issues with cloud access to my Hubitat. At that time I thought that logging out of the app, uninstalling it, and reinstalling solved all the issues. However, due to the current lockdown, and having never once had an access issue from home wifi. I never had cause to follow this cloud issue through, and I totally forgot about it.
However, having just left the house for the first time in nearly three months I realised that when away from home, the security system and camera system that gets triggered by the non-presence of persons in the home did not switch on. Very quickly I discovered that the reason for this was that there was no cloud access to the Habitat. - "No response from hub".
As the Rule Machine routine involved requires the non-presence of two phones, one of them being mine, I decided to check the other phone to see if that could access the Hubitat through the cloud while I was unable. It turned out that the other phone was able and has been so every time that I have checked since.
This issue seems to have started when the OS was updated to Android 10. There is now quite an extensive level of permissions that can be allowed or refused for each app. I did allow all the permissions that were asked for by the app.
I have since tried removing the app and reinstalling it again. I thought that all was well for a couple of days, but I'm back again to 'No response from hub'. There has never once been an issue when connecting from home wifi.
Any suggestions as to how to proceed with trying to solve this would be very welcome.
The phone is a Xiaomi Mi9T Pro
