Thank you for getting back, @urbancowboy1994. 

I appreciate you for performing the troubleshooting to fix the error. We'll surely keep our eye on this concern so you can work with your bank transactions as before.

If I may ask, have you tried logging in to your banks' websites to check for alerts or notifications that need attention? This can be a factor why banks aren't updating in QuickBooks Online (QBO). If not, you can sign in to each bank's website and see any new terms of service, an announcement about maintenance, or other site changes and a recent offer. Please make sure that there are no pending notifications from your online banking account.

Otherwise, you can reach out to our Support Team during their business hours so an agent can look into your this securely and investigate the possible causes of the error message.

Our live support is open M-F 6 AM to 6 PM PT and Saturday 6 AM to 3 PM PT.

In the meantime, you may upload your entries manually through a WebConnect file to get your accounts up to date.

Download the transactions from your bank:

1. Sign in to your bank or credit card's website.
2. Follow your bank's instructions to see how to download CSV files of your transactions to your computer.
3. Check the date range for the download. It will need to be at least one day before the date of your oldest transaction.
4. Download your transactions. Then, save the file somewhere you can easily find it, like your computer's desktop.

Upload them to QuickBooks:

1. Go to the Banking menu. 
2. Choose the blue tile for the account you want to upload the transactions into. 
3. Pick the Link account dropdown. Then, hit Upload from file. 
4. Tap on Browse, then select the file you downloaded from your bank. Hit Next. 
5. From the QuickBooks account dropdown, choose the account you want to upload the transactions into. Then, click on Next. 
6. To match the columns on the file with the correct fields in QuickBooks, please follow the onscreen steps. Tap on Next when finished.
7. Select the transactions you'd like to import, then click on Next. 
8. Hit Yes. 
9. Once you're ready, tap Let's go.

When everything is in place, you're now ready to categorize the transactions to put them into the correct accounts. Then, proceed with your reconciliation to keep track of your statements and balances.
