The QuickBooks error code 108 is an online banking error that occurs when QuickBooks detects unread messages, alerts, or notifications on your bank or credit card’s website. 

These messages block QuickBooks from automatically syncing the transactions among the bank accounts until they are acknowledged by the respective person.

The error usually happens because your bank has posted important information such as new terms, scheduled maintenance notices, or account alerts that require your attention. 

If these messages remain unread, QuickBooks cannot establish a proper connection with the bank’s servers.

This error typically shows up while trying to connect your bank account to QuickBooks Online or when attempting to download or refresh transactions. It often interrupts the banking sync process, preventing new data from being imported.

The typical error message:  

Users may see a pop‑up notification similar to:

“QuickBooks has received a message from your bank that requires your attention. Please log in to your bank’s website to review the message before continuing.”

Frequently Asked Questions:

Does QuickBooks Error 108 mean my bank account has been compromised or hacked?

Error 108 is strictly a notification-based error, not a security breach. It simply means Intuit’s servers tried to access your bank to download transactions, but the bank’s website “blocked” the entry with a pop-up message (like a new Terms of Service, a promotional offer, or a maintenance alert) that requires a human to click “OK.” Your financial data and credentials remain secure.

Can I manually import my bank transactions while waiting for Error 108 to resolve?

Yes. If Error 108 prevents the automatic feed from working, you do not have to stop working. You can use Web Connect files:
➜Log in to your bank’s website.
➜Download your transactions in a supported format (.CSV or .QBO).
➜In QuickBooks Online, go to the Banking/Transactions tab and select Upload from file. This allows you to keep your books current even if the automatic connection is temporarily blocked by the error.

Why does Error 108 sometimes resolve itself without any action from me?

This often happens if the error was triggered by temporary bank site maintenance.
➜If your bank is performing server updates, they may display a “Site Down for Maintenance” banner on their login page. This banner acts like a “message” that triggers Error 108 in QuickBooks.
➜Once the bank finishes maintenance and removes the banner, QuickBooks can successfully log in again during its next automatic update attempt, effectively “fixing” the error on its own.

Can changing my bank login credentials cause QuickBooks to temporarily stop downloading transactions?

Yes. If you change your username, password, or enable new security settings (e.g., 2-step verification), QuickBooks will pause the connection until you re-authenticate.
This behavior is verified by Intuit, as QuickBooks must use the same credentials you use to log into the bank website.

Can browser privacy settings impact QuickBooks Online’s connection to my bank?

Yes. Intuit acknowledges that certain browser settings—like pop-up blockers, tracking protection, cache issues, or strict privacy modes—may prevent QuickBooks from opening your bank’s verification windows or update prompts. While this doesn’t directly cause Error 108, it can prevent QuickBooks from completing the connection process once you clear your bank’s alerts.

Is it safe to refresh or re-connect my bank account in QuickBooks Online when seeing Error 108?

Yes. According to Intuit’s security practices, refreshing your bank feed, updating credentials, or reconnecting your account does not risk data loss.
➜Intuit uses secure, encrypted bank-feed connections (OAuth/Open Banking compliant).
Refreshing only pulls the latest bank data and does not modify your existing transactions.
