Hi @eastsidetommy,
There are several reasons why you'd see error code 101 when you connect your online bank account.
Go through these steps to resolve it:
- Log in to your online bank's website. Check if you're able to sign in without any issues.
- Check if the bank account is active. A bank account is active if it has an existing balance or transactions within the past 12 months.
- Scroll through your messages to see if there's a prompt that awaits your confirmation. Acknowledge them as you go.
After that, you can refer to this article: Categorise and match online bank transactions in QuickBooks Online. It's a guide on how you can download your bank transactions, as well as the steps on how you can match them to your existing transactions.
I'll be around in case you need further assistance with online banking in QuickBooks Online. Post a reply, and I'll take care of it.
