Having an issue ever since upgrading my controller to 4.3.5.  I am running it on a Linux VM which shuts down every few days for a snapshot backup at the same time in the morning.  It seems that when the VM / controller are shut down and restarted I get an alert that the [WAN] of Router is down in the dashboard, and the internet on the network does in-fact drop out for 5+ minutes judging from the plethora of emails I get about my cameras going offline.  I can also duplicate the issue if I shut down the controller for a few minutes, then restart it. 

I haven't gotten far enough into testing to see exactly when it happens, but I believe it may be upon the controller starting back up going through and "re-adopting" the devices.

This was not an issue running on the previous 4.1 and 4.2 versions, and the backups / etc have been running this way for months without problems.  Did something change in the 4.3 version in the startup / adoption process?  Is there any way to roll back to 4.2.11 to test this problem?

EDIT:  Still not fixed in 4.4.3
