"Our systems have detected unusual activity coming from your system. Please try again later."

I’ve been getting the error message in the title all day. Really annoying. The only “unusual” thing I’ve been doing is using it, which I’ve been doing for a year.

Does anyone know how to fix it? I’ve heard of people getting their accounts closed because OpenAI thought they were spambots. I don’t use any plugins. I’ve just been using my custom GPT for the last couple of weeks.
