Welcome to the Community, sales-time2bloss.
Error 103, usually means the user ID or password is incorrect for the bank account you’re trying to connect. First thing you'll need to do if you get this banking error is to login on your bank's website and make sure you have the correct user ID and password for the bank account.
Once done, let's log in to QuickBooks through a private browser and update the bank information from there. It helps us get rid of unexpected behaviors that are sometimes caused by stored cache files.
Let me show you how:
- Go to the Banking page.
- Click the blue bank tile you'll need to update.
- Select the pencil icon and click Edit sign-in info.
- Update the information.
