Access key verification failed : access key not found (Code = 40110000)

Hey, I woke up today to find my trading bot chunking out this error.

I was a bit surprised, since I had not reset my keys.

I logged into my account and it appears you changed your key algorithm. There is no longer a secrets available in the UI and the key presented is completely different than my old keys.

I checked your documentation and its using the old key paradigm.

What is this? How do you just change your entire authentication paradigm overnight with no warning and no update to the documentation?

Hey @Adam_White – can you send an email to with your account email address so we can take a detailed look at your account? Its best to move this to a more secure channel.
