Please double check the following the steps:
- Create a brand new key (some exchanges do not allow an old key to be used again)
- Ensure that you have enabled all the requested read-access permissions per the instructions on the add exchange page.
- Ensure that the API key is activated via two-factor authentication and email confirmation (if applicable)
- Confirm that you have not implemented any IP restrictions (we plan to support this in the future)
- If you are still having problems, please reach out to support
