How to Fix QuickBooks Banking Error 108

QuickBooks Online displays: "The bank needs you to do something at their site (108)" or "There's a message on your bank's website that needs your attention"

Error 108 appears in QuickBooks Online and QuickBooks Self-Employed. At QuickFix Bookkeeping, the precise definition: Intuit's servers connected to your bank successfully, but found a message or alert on the bank's website requiring a human response before the data download can proceed. Your financial data is secure — Error 108 is never a security breach.

The QuickFix Bookkeeping Distinction — Why Pop-Up Blockers Are the Hidden Cause

Error 108 always originates from the bank side — but the most common reason users cannot resolve it is that a pop-up blocker hides the bank's alert, making them think there is nothing to action when there actually is.

Scenario 1 — Linking a New Account

Message: "The bank needs you to do something at their site." The bank requires you to complete an action (accept new T&Cs, verify your identity, grant permission to a third party) before it will allow QBO to connect. Log into the bank website and look for any pending alert or prompt in your notifications or inbox.

Scenario 2 — Existing Connected Account

Message: "There's a message on your bank's website that needs your attention." A bank notification appeared after a previously working connection. Common triggers: new T&Cs requiring acceptance, a promotional prompt, a security verification requirement, or a maintenance notice.

The pop-up blocker hidden-alert problem: Many bank notifications appear as pop-ups or inline banners that are suppressed by browser pop-up blockers or antivirus software. Users log into their bank, see "You're all caught up" or no visible alerts, and conclude there is nothing to action — but the bank still shows Error 108 to QB. The fix: disable the pop-up blocker in your browser settings, then log into the bank again in a fresh session and look carefully for any prompts or notification badges. Incognito/private mode with no extensions is another reliable way to see alerts that blockers normally suppress.

What Causes QuickBooks Banking Error 108?

Unread Bank Alert Requiring Action

Primary cause in most Error 108 cases — your bank has posted a message requiring your attention before it will allow the data connection to proceed. Common alerts: new Terms of Service requiring acceptance, security verification prompts, promotional offers requiring acknowledgement, or identity verification for new regulations. QB cannot proceed past these until a human interacts with them on the bank's website.

Pop-Up Blocker Hiding the Bank Alert

A browser pop-up blocker or antivirus with built-in ad blocking suppresses the bank's alert pop-up. The user sees the bank's main dashboard but never sees the alert — leading them to believe there is no action to take. The bank still considers the alert unactioned and continues to block QB's access. Disabling the pop-up blocker and logging into the bank again in a fresh session reveals the hidden alert.

Wrong Credentials Stored in QBO

If you changed your online banking password recently and QBO still has the old credentials stored, the connection fails. Bank-side failure to authenticate can manifest as Error 108 when the bank's response includes a redirect to a message requiring you to verify your identity with correct credentials. Disconnecting and reconnecting with the current credentials resolves this.

Bank Server Maintenance or Temporary Outage

The bank's online banking servers are temporarily down or under maintenance. In this case, Error 108 appears because QB cannot reach the bank's data at all — the "message" is effectively the bank's maintenance page. Wait 2–3 hours and try again. Check the bank's status page or call their support to confirm whether online banking is operational.

Bank Changed Its Online Banking Infrastructure

After a bank merger, rebrand, or major technology upgrade, the connection method or authentication requirements change. QBO's stored connection may no longer match the bank's new requirements — producing Error 108 as the bank presents a new onboarding flow. Disconnecting and reconnecting the bank account in QBO forces a fresh authentication that works with the new infrastructure.

Multiple QB Versions or Conflicting Extensions

Having multiple QB Desktop versions alongside QBO, or conflicting browser extensions (banking security extensions, VPNs, or ad blockers), can interfere with QBO's bank connection handshake and produce Error 108. Using an incognito browser window without extensions, or a different browser entirely, often bypasses this conflict.

How to Fix QuickBooks Banking Error 108

Start with Method 1 — visit the bank's website directly and clear all alerts. This resolves Error 108 in the vast majority of cases.

METHOD 1 Log Into Bank Website + Disable Pop-Up Blockers First Do this first — resolves most Error 108 cases
1

Disable pop-up blocker first: In Chrome → three-dot menu → Settings → Privacy and security → Site settings → Pop-ups and redirects → turn off "Block." In Firefox → Preferences → Privacy & Security → Permissions → uncheck "Block pop-up windows." In Safari → Preferences → Websites → Pop-up Windows → set to Allow. Alternatively, open an incognito/private browser window — extensions including pop-up blockers are typically disabled in incognito mode.

2

Log into your bank's website using the same username and password you used to connect the bank in QBO. Check every part of the dashboard for alerts: notification bell, inbox, message centre, banner notifications at the top of the page, and any overlay pop-ups. Action every alert — accept T&Cs, dismiss promotional notices, complete any verification steps.

3

Sign out of the bank website. Return to QBO → Banking → click Update (or the refresh arrows on the bank tile). If the connection now downloads transactions — Error 108 is resolved. If it still shows 108 — wait 2–3 hours and try again (some bank alerts take time to clear on their servers after being acknowledged).

METHOD 2 Update QBO Bank Connection Refresh the connection after clearing bank alerts
1

In QBO → Banking (or Transactions → Banking) → find the affected bank account tile. Click the Update button (or the circular arrows). If the bank tile shows an Edit button or pencil icon → click it → select Update bank info. This forces QBO to reconnect with the bank's servers and check for alerts again — if you cleared them in Method 1, the connection should now succeed.

METHOD 3 Disconnect and Reconnect the Bank Account Credentials changed or connection infrastructure changed
1

In QBO → Banking → click the bank account tile → Edit (pencil icon) → Disconnect this account on save → Save and close. After disconnecting, wait 1–2 minutes. Go back to Banking → Add account → search for your bank → connect with your current, correct login credentials. Make sure you are using the exact same username and password you use to log into the bank's website directly — not a QuickBooks account login. A fresh reconnection re-authenticates from scratch and bypasses stale connection state that can cause persistent 108 errors.

METHOD 4 Import Transactions Manually While Error 108 Persists Keep books current during troubleshooting
1

Log into your bank's website. Download transactions in .CSV format for the period affected by Error 108. In QBO → Banking → the affected account tile → click the File upload button (or Transactions → Upload from file). Map the columns (date, description, amount) → import. This bypasses the automatic connection and keeps your books current while you resolve the underlying Error 108. You can also use a .QBO Web Connect format if your bank supports it — this maps directly without column mapping.

Frequently Asked Questions

Is Error 108 a security problem? Has my account been compromised?
No — Error 108 is not a security incident. Per Intuit's own documentation, it is a notification-based error that signals your bank has a message requiring your attention before the data connection can proceed. It has nothing to do with your account being compromised, unauthorised access, or any kind of security breach. Your bank credentials and financial data remain completely secure. The error is essentially QB saying "your bank wants you to check something on their website before I can download your transactions."
I visited my bank's site and saw no alerts, but still get Error 108. What now?
The most common reason for this is a pop-up blocker hiding the alert. Try these steps: (1) Open an incognito/private browser window — extensions including pop-up blockers are disabled by default in incognito mode. (2) Log into your bank website and watch carefully for any overlay, banner, or pop-up that appears during or after login. (3) Check your bank's notification centre, message inbox, and any "Action Required" sections — some banks bury alerts in non-obvious locations. (4) If you still see nothing, contact your bank's online banking support and ask if there are any pending alerts, terms acceptance requirements, or messages associated with your account. Banks can see these on their backend even when you cannot see them in the UI.
Can I keep my books updated while waiting for Error 108 to resolve?
Yes — use the manual file upload method (Method 4). Log into your bank's website, download your transactions in CSV format for the affected period, and upload them to QBO via Banking → Upload from file. This lets you categorise and match transactions normally while the automatic connection is blocked. Once you resolve Error 108 and restore the automatic connection, QBO is smart enough to recognise transactions that were already uploaded manually and will not create duplicates — it matches by date, amount, and description. Your books stay accurate throughout the error period.
