There are several reasons why you're getting the 324 connection error, Dylan.
Sometimes this happens due to the following reasons:
- Your bank or credit card company changed the account or moved it to a new server.
- You changed the account name or other information on your bank or credit card company's website.
- Your bank or credit card company issued a new account or credit card.
- You closed your bank or credit card account.
You can update and check your connection to make sure that software runs smoothly. I've outlined the steps below:
- Sign in to QuickBooks Online.
- Go to Transactions, then select Bank transactions.
- Click Update.
- If you still see the error, look for a banner on the Banking page. Select the Check connections link and follow the prompts provided to fix the issue.
But if you have a new account number, or got a new card, and wants to keep your old account, disconnect accounts connected.
- Go to Transactions, then Bank transactions.
- Select the tile for the bank account.
- Click the pencil icon, then select Edit account info.
- Choose the Disconnect this account on save checkbox.
- Hit Save and Close.
Once done, connect or link the new accounts to your chart of accounts.
