Hmm... what else has changed? Does this container have good drainage? If not I would suspect a rot problem. Let the soil dry just a little in between watering. If you suspect infection, you can add a little wettable sulfur to the soil to help with this.
This can happen if the roots get disturbed to much as well. Here is an article for the care of these plants:https://www.gardeningknowhow.com/ornamental/flowers/chrysanthemum/growing-mums-in-containers.htm
