Before you do those ways to fix it, please check that you indeed have enough iCloud storage available for your device. Then follow the below methods to solve problem.

Method3. Delete the existing iCloud backup for your device
If the aforementioned solutions are not working, you can simply try this out. This solutions has worked greatly for some users even though it is a little bit dangerous. Generally iCloud doesn't create any conflict but sometimes it can be. That is why this can be a solution as well.
