How to Fix ‘Conversation Not Found’ Error in ChatGPT


Chatbots and conversational AI systems have become increasingly popular for providing automated support and enhancing user experiences. ChatGPT, powered by OpenAI’s GPT-3.5, is one such powerful tool. However, users may encounter errors when interacting with ChatGPT, one of which is the ‘Conversation Not Found’ error. In this blog, we’ll explore what this error means and how to resolve it effectively.

Understanding the ‘Conversation Not Found’ Error in ChatGPT

The ‘Conversation Not Found’ error typically occurs when you are using ChatGPT to maintain a conversation context and the system can’t find the conversation you’re referring to. This often happens in interactive sessions where you are having back-and-forth interactions with the AI. The error message can be frustrating, but it’s usually due to a simple issue that can be fixed.

Common Causes of the Error

There are a few common reasons why you might encounter the ‘Conversation Not Found’ error:

  1. Incomplete Conversation State: If you haven’t provided a complete conversation history to the AI model, it won’t be able to locate the conversation context. Ensure that you pass the entire conversation history, including both user and AI messages.
  2. Empty Context: Sometimes, users mistakenly send an empty message, which can reset the conversation context. Make sure you’re not sending empty or incomplete messages to ChatGPT.
  3. Timeout: If your conversation has been idle for too long (e.g., more than two minutes), the context may expire, and you’ll have to start a new conversation.

Tips to Resolve the Error

Now that you know why the error occurs, let’s look at some tips to help you resolve it:

  1. Maintain a Complete Conversation: Always send the full conversation history, including user and AI messages, to ChatGPT. This ensures the model has the necessary context to respond accurately.
  2. Check for Empty Messages: Review your conversation inputs for any empty or incomplete messages. Ensure that every user message makes sense and adds to the ongoing conversation.
  3. Manage Timeouts: Be aware of the conversation timeout, and if necessary, restart the conversation by creating a new one to maintain context.
  4. Use System Messages: System messages can be helpful in setting the context at the beginning of the conversation and guiding the AI throughout the conversation.
  5. Experiment and Iterate: ChatGPT’s performance can improve with experimentation and iteration. Try rephrasing your messages or reorganizing the conversation to get the desired results.

Reporting Persistent Issues

If you continue to face the ‘Conversation Not Found’ error despite following these tips, it’s a good idea to reach out to OpenAI’s support or community forums for further assistance. They can provide additional guidance and help you troubleshoot more complex issues.


The ‘Conversation Not Found’ error in ChatGPT is a common challenge for users engaging in dynamic and interactive conversations. However, with a good understanding of why it occurs and the tips provided in this blog, you should be able to resolve the error and have more successful interactions with the AI model.

Remember that ChatGPT is continually improving, and OpenAI’s team is actively working to enhance the user experience. By staying informed and following best practices, you can make the most of this powerful conversational AI tool.
