Suddenly my chatgpt can't roll any dice

I have been playing DND with chatgpt for about a week and it was amazing it controlled the enemies and narrated all the action and rolled the dice very well and very randomly and it was very good at targeting random party members aswell, and then all of a sudden it just said " I’m sorry I seem to have encountered a problem" whenever I asked it to perform any kind of dice roll, and the problem persist even if I open a new chat
Can anyone explain what might be the cause of this?
