How to resolve the bank fee keep disconnecting issue?

To better assist you, could you confirm which bank you are trying to connect to QuickBooks Online? The AUT002 error occurs when QuickBooks Online cannot authenticate your bank connection, usually due to expired security tokens, MFA issues, or outdated login credentials.

To troubleshoot this, follow these steps:

1. Log in directly to your bank’s website and check for any security alerts, multi-factor authentication (MFA) prompts, or re-verification requests that need your action.
2. Confirm whether your bank recently updated its security settings, login process, or credentials.
3. When reconnecting the account in QuickBooks Online, make sure you use the correct and current login credentials. Avoid using autofill and manually enter your username and password.  

Once you confirm the bank name, we can provide more specific troubleshooting steps if needed.
