Hi there, userjared1.
Are you getting any error codes, so we can check to see if this is an emerging issue?
If you don't get any error codes or messages, please follow the troubleshooting steps in this article: What to do if you get a bank error or can't download transactions in QuickBooks Online.
On the other hand, you can manually upload the transactions of the affected period, so you can match them with your QuickBooks transactions or add them to your books.
Feel free to go back to this thread if you need more help with online banking.
