Floodlight Cam offline

I have had the floodlight cam for 3 weeks and it has been working wonderfuly until Sunday. 2 days ago the cam went offline for live view. If you go back through the time line, you can see that it has recorded and you can see that fine. Also in the first small screens where it shows all your cameras in mini view you can see it is working....but black screen in live view. It did go back on line for a few times that I checked yesterday, but is totally out again as of last night and today. Once in awhile it will start to pixelate a picture but barely. I also have a doorbell 2 .....I have had no problem with it at all. My husbands Cell phone display is the same and also our tablet that has the ring app installed on acts the same way. Any idea of the problem and for sure how do we get it back to normal........Thanks
