AI doesn’t want to answer questions

So I have the chat GPT Plus. Which has internet access. Now I started a conversation talking about the chances of a nuclear fallout with Chat GPT. I tried the advanced voice and we previously to that topic it talked smoothly. The moment I started asking about the topic for some reason it started saying it can’t hear me. As we continued I asked it to search the web to be prepared for this conversation as concise as it can. Interestingly so it acted as if it cannot complete such a task. I then opened a new chat and asked it some random question and it searched the web. Weird what do you think?
