When ChatGPT login is not working, you may see an error message, be missing the option to log in, or experience one of the following situations:

ChatGPT requires a lot of system resources to run and OpenAI can’t always keep up with the demand. When too many people try to use ChatGPT at the same time, it can cause problems with the servers, including login failure.

In most cases where you are unable to login to ChatGPT, stuck in a login loop or see a 503 server error, this is due to server congestion. Other issues with the ChatGPT servers that are not related to congestion can also prevent you from logging in.

In other cases, ChatGPT login issues are caused by login issues, such as entering an incorrect email address or password. Network connectivity issues, including Virtual Private Network (VPN) issues, can also prevent you from logging into ChatGPT. Corrupt browser cookies and other data, poorly functioning browser extensions, and other related issues can also cause problems.
