How to Fix QuickBooks Banking Error 324
A bank feed that was working has stopped and QuickBooks shows: "Error 324: We can't find this account at your bank. Let's make sure the right accounts are connected to QuickBooks."
Error 324 is a broken connection — QuickBooks had this account connected and working, then lost it. Something changed at the bank after the connection was established. At QuickFix Bookkeeping, the first question is: what changed at the bank since the feed last worked?
The QuickFix Bookkeeping Distinction
Error 106 and Error 324 both say "we can't find this account" — but they represent completely different situations and need different fixes.
Error 106 — never found
Credentials work but the account was never visible. Account closed, wrong portal, or account number changed before connection was established.
Fix: investigate the account at the bank, reconnect with correct details.
Error 324 — this page — was found, now lost
The connection was working, then the account vanished from the bank's feed. Something changed at the bank after the connection was made.
Fix: disconnect and reconnect with updated account details. Always a full reconnect.
Why 324 always requires a full disconnect and reconnect: When QuickBooks connects to a bank account, it stores an internal identifier for that specific account in the bank's system. When the bank changes the account number, migrates to a new server, or restructures how accounts are presented, that stored identifier no longer matches anything in the bank's current account list. QuickBooks cannot update this identifier automatically — it requires a full disconnect (removing the old broken identifier) and a fresh reconnect to create a new valid one pointing to the current account.

What it means
Error 324 means the bank account that was previously connected and syncing successfully can no longer be found by QuickBooks. The connection's stored account identifier no longer matches any active account in the bank's system — the account changed, moved, or was closed after the connection was established. This always requires a fresh connection.
Your downloaded transaction history is safe. Transactions already downloaded and accepted into QuickBooks are stored in your company file and are unaffected by a broken bank feed connection.
What Causes QuickBooks Error 324?
🔢
Account Number Changed
Most common cause — the bank issued a new account or card number after a fraud event, security upgrade, or routine card renewal. QuickBooks' stored identifier references the old number which no longer exists in the bank's system.
🏦
Bank Migrated to New Server or Platform
The bank migrated accounts to a new system, changed their online banking platform, or updated how account data is presented to third-party applications. The old connection path no longer maps to the account.
💳
Credit Card Renewed or Replaced
A credit card was renewed with a new card number, replaced after a fraud report, or upgraded to a different card product. The new card number creates a new account identifier at the bank — the old connection references the previous card which is now inactive.
❌
Account Closed
The bank account was closed after the QuickBooks connection was established. A closed account is removed from the bank's active account list, so QuickBooks returns 324 on the next sync attempt.
💳
American Express Security Tightening
American Express tightened third-party access requirements. Individual cards under a parent AmEx account now need to be connected using the card's own name, not the parent account. Connections made before this change produce persistent 324.
📋
Duplicate Account Names in QuickBooks
Two bank accounts in QuickBooks have identical names. QuickBooks cannot distinguish which account to reconnect and returns 324 when trying to re-establish the feed. Renaming one account to a unique name resolves this specific variant.
How to Fix QuickBooks Banking Error 324 — Step by Step
Error 324 always requires a disconnect and reconnect — the stored identifier is broken and cannot be patched. The question is what details to use for the reconnect.
METHOD 1
Use the "Reconnect My Account" Link If Visible
Fastest fix — QuickBooks guides you through it
When Error 324 appears, QuickBooks sometimes shows a "Reconnect my account" link directly in the error message. This is the fastest resolution path — click it and follow the prompts to select the updated account.
1
In the Error 324 message — click "Reconnect my account" if it appears.
2
You will be taken to your bank's website. Log in with your current credentials. Select the account that should be connected to QuickBooks.
3
Confirm the account in QuickBooks and set the correct account type. The connection is refreshed with the current account details.
QuickFix tip: If the "Reconnect my account" link is not shown, or if clicking it doesn't resolve the error, proceed to Method 2 for a full manual disconnect and reconnect.
METHOD 2
Disconnect and Reconnect the Bank Account
Standard fix for all 324 variants
A full disconnect removes the broken stored identifier. The fresh reconnect creates a new valid one pointing to the current account. This does not delete any previously downloaded transactions.
1
In QuickBooks Online → Bookkeeping → Transactions → Bank Transactions. Find the account showing 324. Click Edit ✎ → Disconnect this account on save → Save.
2
Click Add account. Search for your bank. Enter credentials manually (no auto-fill). When the account list appears — confirm the account you need is visible and select it.
3
Set the start date for transaction download to the day after the last transaction already in QuickBooks — to avoid downloading duplicates. Click Connect.
QuickFix tip: Before reconnecting, note the date of the last successfully downloaded transaction in the account (visible in Bank Transactions). Use the day after that as your reconnect start date. This prevents the same transactions downloading twice and creating duplicates that need manual cleanup.
METHOD 3
Rename Duplicate Account Names
Two accounts with the same name in QuickBooks
If two bank accounts in QuickBooks have identical names, QuickBooks cannot determine which one to reconnect when the 324 error prompts a reconnect. Renaming one account to a unique name resolves the ambiguity.
1
Go to Settings → Chart of Accounts. Check whether any two bank accounts share the same name. If yes — click Edit on one and rename it with a distinctive name (e.g. add "- Business" or the last 4 digits of the account number).
2
After renaming — attempt the disconnect and reconnect (Method 2). With unique names, QuickBooks can correctly identify and reconnect the right account.
METHOD 4
American Express — Connect Each Card Individually
AmEx parent/sub-card structure
American Express tightened its third-party access requirements. Cards under a parent AmEx account must now be connected to QuickBooks using the individual card's name — not the parent account. This is the specific AmEx fix confirmed in Intuit's community.
1
Disconnect all existing AmEx connections showing Error 324.
2
When adding accounts back — search for your card by its specific card name (e.g. "American Express Blue Business Cash") rather than just "American Express." Connect each card separately using that card's individual connection, not the parent account.
3
If transactions from multiple sub-cards are now showing under one account — this is a separate known AmEx issue. Disconnect all, then reconnect each card using its individual name as separate connections.
METHOD 5
Manually Import Transactions While Resolving
Keep books current during the gap
While you are working through the reconnection process, manually import transactions from the bank to prevent a gap in your books. Most banks allow CSV export from the account activity page.
1
Log into your bank website → download transactions as CSV for the period since the last successful sync.
2
In QuickBooks Online: Bookkeeping → Transactions → Bank Transactions → Upload transactions. Select the account, upload the CSV, map columns, and import. Once the live feed is restored, do not re-download the same date range to avoid duplicates.

Frequently Asked Questions
Will I lose any transaction history when I disconnect and reconnect?
No. Disconnecting a bank feed only removes the live connection — it does not delete any transactions already downloaded and accepted into QuickBooks. Your transaction history, categorisation, and reconciliation records are stored in your QuickBooks company data, completely separate from the bank feed connection. When you reconnect, set the start date to the day after your last downloaded transaction to avoid downloading duplicates. You will then receive only new transactions going forward.
How is Error 324 different from Error 106?
Both errors produce the same message — "we can't find this account at your bank" — but they happen in different contexts. Error 106 occurs when setting up a new connection: QuickBooks logs in successfully but cannot find the account in the bank's account list. The account was never successfully connected. Error 324 occurs with an existing connection that was previously working: QuickBooks connected to the account successfully in the past, downloaded transactions, and then on a subsequent sync attempt the account can no longer be found. Something changed at the bank after the connection was established. Error 324 always requires a full disconnect and reconnect with updated account details. Error 106 requires investigating what the correct account details should be.
My reconnect worked but transactions are now duplicating — how do I prevent this?
Duplicates happen when the reconnect start date overlaps with transactions already in QuickBooks. When reconnecting after a 324 error, check the date of the last transaction successfully downloaded before the error appeared. Set your reconnect start date to the day after that transaction. If you have already created duplicates, go to Bank Transactions, find the duplicate entries (they will appear twice), and exclude the duplicates using the Exclude option — do not delete the originals that are already matched and reconciled.
