I have checked all options and everything is set to sync. In my Android setting, everything is checked to sync. I've no idea why my new photos will not back up to my Google photos account any more. Any help appreciated!

Google may have recently addressed this issue:
Open the photos app
Hit menu icon (Top Left)
Select "About Google Photos" (Bottom of List)
Select the options menu (Top Right)
Select "Help and feedback"
The first thread there fully answered my questions regarding my photos not syncing. It was entitled "My photos aren't backing up" and was under the "popular" heading. There are a few reasons this might happen and this article seemed to address them all. Following it I was able to get my Droid Turbo (lollipop) to sync photos within minutes. Follow the steps exactly. Hope this is helpful.
