Error when trying to authenticate - https://chat.openai.com/?_tm=c_err

Hello OpenAI Community,

I’m reaching out to seek help and advice regarding an authentication error that I’ve encountered while trying to access a specific URL for authentication purposes.

Error Description:
When attempting to authenticate on the following redirect URL:
[https://chat.openai.com/?_tm=c_err]

Any ideas what is going on? I get the Oops, an error occurred! Try again.

When url redirects are the chat.openai.com and the url of the GPT in question.
