Thanks for joining this thread, @tkoni.

I appreciate you trying some tests to resolve the Canadian Imperial Bank of Commerce (CIBC) Error 103 you're getting. I can help you get around with this and share some insights.

I've checked my tools, and I was able to confirm that there's an open investigation about Error 103 with CIBC.

While our banking team is communicating with your financial institution, we'd like to add your account information on our list of affected users. Once added, our engineers will see how widespread this is, as well as any common components between those affected. You'll also get automatic email updates.

To get the details of our new contact directory, you can check this link: Contact the QuickBooks Online Customer Support team.

Thank you for understanding. Let me know how the call goes. I will also get back into this thread once I get an update.
