ChatGPT, the chatbot from OpenAI, is one of the fastest growing tools on the internet, having reached a user base of 100 million in just two months! Currently, ChatGPT serves approximately 13 million daily active users. To scale to this proportion in such a short time is just astounding. However, due to a large number of users swarming in like bees, ChatGPT often crashes, is at capacity, or cannot generate responses, and users complain that it does not work reliably. Some users report ChatGPT error codes like 1020 and 429. Especially after the release of the latest GPT-4 language model, the downtime has increased. The chatbot encounters internal server errors intermittently, and sometimes ChatGPT refuses to open. If you're searching for fixes or googling "ChatGPT down" when the service isn't working, follow our guide to learn how to fix ChatGPT errors.

In this article, we have explained all the ChatGPT errors and their fixes. If ChatGPT is not working on your device, expand the table below and get started with the proven solutions.

The first and most common ChatGPT error code is "Error 1020. Access denied." This usually happens when ChatGPT finds something unusual with your network or device and therefore blocks your access. It can also occur if ChatGPT detects misconfigured VPN settings on your device. Basically, ChatGPT enforces certain security measures before you can access its service, and if your device or network doesn't comply, it will show Error 1020.

ChatGPT returns error 429 when you make too many requests to the server in a short period of time. If you are using the OpenAI API to use ChatGPT, this error means that you have exceeded the maximum number of requests in a given time. To ensure fair use, ChatGPT sends error 429.
