unable to get transactions for 1 account. error 187

Hello there, David.

The error you're experiencing occurs during Multi-Factor Authentication (MFA) when the security data sent during app approval doesn't match the bank's expectations, leading to a sign-in failure.

To resolve the issue, log in to your CBA account via the website or app to check for alerts or security blocks. Ensure third-party access permissions for QuickBooks are enabled. Then, manually enter your credentials instead of using autofill.

You can also consider switching to a direct feed for a stable link between CBA and QuickBooks, allowing automatic and stable transaction flow without manual approvals. Start by following this article: Connect Commonwealth Bank direct feeds.
