Hi bburches and vlsheffield,
Thank you for reporting. Normally, error 103 will be resolved by reentering your login credentials, as suggested in the article. Since the steps didn't resolve the issue, I would recommend contacting our QBO Support tomorrow from 6 AM to 6 PM PT. This way, they can use more tools to check this further.
In the meantime, you can download the missing transactions to a supported Web connect file and upload them to the Banking page. You can refer to this article: Manually upload transactions into QuickBooks Online.
Feel free to go back to this thread if you have any other concerns.
