Before proceeding, may I know your Financial institution? Can you share the troubleshooting you've done? It will help me verify if there are any reports related to your bank.

The bank error 103 occurs when the user ID or password for the bank account you’re trying to connect to is incorrect. If you made changes to your sign-in credentials through the bank’s website, you'll need to update QuickBooks.

If it's your first time linking your bank to the program, log into your bank’s website and ensure your credentials are entered manually and not auto-filled by your computer. If you succeed, connect again through QuickBooks by manually entering your credentials.

Try opening your QBO account on any private/incognito browser. If the same error persists, consider having MT Online or one of the converter tools (e.g csv2qbo @ $60 on time license) as a workaround.
