Check if there's possible contamination. One wrong strain of bacteria can pretty much ruin any fermentation. I'd say look at your yogurt under a microscope but I doubt you have one, so just make sure everything is clean and nothing that isn't supposed to be in there falls into your yogurt.

Thank you so much! I didn't think about that... I will definitely be more cautious to possible contamination next time!
