Does not connect to my bank it says try a again in a few hours

Good day, collinsraymond.

Let's work together and get this sorted out.

When you're unable to connect your bank, please make sure to check the following:

• Open a new tab and log in to your bank's website to see if you can get in without any errors.
• Check if your account is active. An account is considered active if there’s an existing balance, or if there were transactions in the past 12 months.
• If you’re supposed to have an active account, but still unable to log in to your bank’s website, contact them directly.
• Look for missed prompts that need your confirmation (ex. terms and conditions).
• Acknowledge the prompt, then go back to your QuickBooks Online account and connect your bank again.

Here's an article for the step by step instructions: Connect bank and credit card accounts to QuickBooks Online.

For the time being, you have the option to manually import your bank transactions by following the steps here: Manually upload transactions into QuickBooks Online.

Once you're able to connect the bank, you may see some duplicate transactions. What you can do is exclude them.

Here's how:

1. Go to Transactions > Banking.
2. In the For review tab, put a check mark on the duplicate transactions.
3. Click the Exclude button.

I have this sample screenshot for a visual reference:

After excluding these transactions, you can delete them in the Excluded section.

I'm also adding this article to help you match and categorize your downloaded transactions: Categorise and match online bank transactions in QuickBooks Online.

You can also share the name of your bank in your reply. This way, we can check for any reported issue about the error. I'll be around to help you out again. Take care and stay safe!
