I've read all this post and I've decided to reply cause i've a similar problem (if not the same one).
Often a camera (not always the same) got an offline message (red circle with the line). The camera is working (i'm using Dviewcam too) and recording correctly. This problem occours only on the Mydlink app. The only way to solve it is to unplug the camera and replug. BTW this is a bit annoying cause i've to go outside, open the case with the powercord and do it...
Any change to solve it?
Thanks
