When you’re trying to connect or update your bank account in QuickBooks Online (QBO) or QuickBooks Self-Employed (QBSE), encountering Bank Error 108 can be frustrating. Fortunately, this is one of the easier banking errors to fix because it doesn’t usually indicate a problem with QuickBooks—it indicates that your bank has an important message that needs your attention.

In this guide, we’ll break down what Error 108 means, why it appears, and the step-by-step methods to resolve it.

What Is QuickBooks Bank Error 108?

Error 108 appears when your financial institution has posted a message that requires you to log in to your online banking website. These messages typically involve:

• Security notices
• New terms and conditions
• Alerts about changes to your account
• Requests to verify personal info
• System or maintenance notifications

QuickBooks can’t access your account until you review and acknowledge these messages.

Common Causes of Error 108

• Unread notifications on your bank’s website
• Bank login credentials updated recently
• Two-factor authentication prompts not cleared
• Browser pop-up blockers affecting bank sign-in
• Bank-side security changes

How to Fix Bank Error 108 in QuickBooks

Step 1: Sign In to Your Online Banking Account

1. Open a new browser tab.
2. Log in directly to your bank’s website (not through QuickBooks).
3. Look for:
   • Alerts
   • Messages
   • Inbox or Secure Messages Center
4. Read and acknowledge all notifications.

Update Your Bank Connection in QuickBooks

Once you’ve cleared the alerts:

In QuickBooks Online

1. Go to Transactions → Banking (or Bank Transactions).
2. Select your bank account.
3. Click Update in the upper-right corner.

Check for Bank Credential Issues

If the error continues:

• Re-enter your bank login credentials.
• Ensure access is not blocked by your bank due to suspicious activity.
• Disable VPN temporarily—some banks block them.

To re-enter credentials:

1. Go to Banking.
2. Select the account.
3. Choose the Edit (✎) icon.
4. Select Edit sign-in info.
5. Update username and password.

Allow Pop-ups for Your Bank and QuickBooks

Some banks display required messages using pop-ups.
If your pop-up blocker is active, you might never see them.

Allow pop-ups in your browser settings for:

• Your bank’s website
• *.intuit.com

Clear Your Browser Cache (Optional but Helpful)

A corrupted cache can interrupt connections between QuickBooks and your bank.

Clear your cache and cookies, then try refreshing the bank feed again.

Try Using a Different Browser

If the issue persists, switch to another browser such as

• Google Chrome
• Firefox
• Edge
• Safari

Sometimes the bank connection works better on an alternate browser.

What if Bank Error 108 Still Won’t Go Away?

If you still see the error:

• Your bank may be having a temporary outage.
• QuickBooks may need to refresh its connection on the backend.
• Additional security steps may be required by your bank.

You can also check your bank’s service status page (if they provide one) or contact the bank’s support.

Preventing Error 108 in the Future

• Log in to your bank regularly to clear new alerts.
• Keep your bank credentials up to date.
• Ensure your browser and QuickBooks app are updated.
• Disable pop-up blockers for your bank and QuickBooks.
• Add your bank to your browser’s trusted sites list.

Final Thoughts

Bank Error 108 in QuickBooks Online and QuickBooks Self-Employed is typically easy to resolve. Since the issue originates from your bank’s side, the solution usually involves logging into your bank account and reviewing any unread messages or alerts.
