Plug in's aren't notifying me of updates

I haven’t gotten any notifications that there were updates for any of my wordpress plugins for a while which I thought was odd…I went to check if there were updates available and there were. So I’m not sure how long I haven’t been getting plug in notifications, and sure what is going on…

I need to figure it out though..I also don’t remember doing anything out of the ordinary that would have caused those notifications to stop coming through. This is a strange one…any help would be greatly appreciated.
