Good day, @tkoni.
I'm updating this post to inform you that the Investigation 28289 is also tagged as closed and resolved. You should no longer have the Error 103 in your QBO.
However, if you're still encountering the error, let's try these recommended steps:
- From the left menu, click Banking.
- Under the Banking tab, highlight the Canadian Imperial Bank of Commerce (CIBC) bank.
- Click the pencil icon.
- Choose Edit sign-in info.
- Enter your credentials and select Update.
That should help you keep going today, @tkoni. Please let me know how it goes or if you have any follow-up questions about banking. I'll be here if you need further assistance. Take care always.
