Hello, lornacullinan-gm.
I'm here to help fix the error message you're getting when connecting your bank to QuickBooks Online (QBO).
Error 103 occurs when credentials entered into QBO don’t match what your financial institution has.
However, since you mentioned that you've entered the correct credentials, let's sign in to your QBO account using a private browser (incognito). There are times that the browser is already full of frequently accessed page resources (cache and cookies), causing some unusual response.
Here's how:
- Press Ctrl + Shift + N (Google Chrome).
- Ctrl + Shift + P (Firefox).
- Control + Option + P (Safari).
Once logged in, try to connect your bank again to double-check. You can refer to this article for the detailed steps on how to do it: Connect bank and credit card accounts to QuickBooks Online.
If it's successful, return to your default browser and perform a clear cache to refresh the system. However, if the issue persists, try using other supported browsers.
