I'm here to provide you a solution to fix this issue, @Christina65.
Thanks for letting us know that you've already reached out to our phone support and with your bank's.
Let me share with you some information on what's causing the error 103. Mostly, you'll get this error code if the credentials that you're using when signing in is being rejected by your bank's website.
Here are the following reasons why you're getting this error:
- You have entered the wrong credentials while trying to connect to your financial institution for the first time.
- You have selected the wrong financial institution.
- If you are currently connected and you’ve updated your credentials with your financial institution. The information in QuickBooks Online is to be updated as well. Otherwise, you might face Error 103 while Logging in to Bank Account.
If you've already checked the following information above, then this can be a browser-related issue. There are times that cached being stored in your browser can cause unexpected behavior with the product. We can clear this out to fix this error.
First, let's use a private browser to verify if the issue is related. You can press this following commands to access this site:
Ctrl + Shift + N (Google Chrome).
Ctrl + Shift + P (Firefox).
Control + Option + P (Safari).
If you're to connect your bank successfully, then let’s go back to your browser and clear the cache. These caches of data are essentially junk files and can be safely deleted to free up storage space.
If the same problem occurs, try using a different browser. This can be an issue with the browser that you use and QuickBooks.
Let me also provide you a link to check if your browser is compatible with QuickBooks: Fixit.intuit.com.
