Hi Khemaienterprises,
Error 324 occurs when QuickBooks is unable to locate or access the bank account or credit card account that you are trying to connect or sync with. This error can be caused by various issues, including incorrect login credentials, changes in your bank's website, or issues on the bank's end.
This may be because:
- Your bank or credit card company has modified the account or shifted it to a different server.
- You've updated the account name or other information on your bank or credit card company's website.
- Your bank or credit card company has provided a new account or credit card.
- You've terminated your bank or credit card account.
- You possess multiple accounts with the same name at the bank.
