QB Issue Resolution:

I can help you fix the business banking site error you’re running into when signing in to Key Bank.

There was actually an investigation about users unable to sign in with Key Bank which has already been resolved. This bank requires enabling third-party apps within their website to establish a connection to QuickBooks.

To resolve it, please log in to the Key Bank’s website and complete the steps to allow third-party access. If you signed up with a third party allowing them an access to your account, you also have to authorize the third-party access within Key Business Online.

To do that, navigate to Manage Security and click the Authorize Access button. For your reference, you can look into this article to fix banking error 103 in QuickBooks Online: https://community.intuit.com/articles/1732186.

That should help you connect with Key Bank.
