Having trouble with connecting my bank, all details are correct but says try again in a few hours.

Hi @userthediamonddetail,

I got your back on this query about your online bank account in QuickBooks Online (QBO).

QBO can sync with several online bank accounts. Some of which have several variants available for connection as well. With that said, the first thing you can check is to see if you have the correct bank account. To proceed, search your online bank account via its URL or web address, instead of its name. This way, you're sure you have the correct account.

If you continue to receive an error message, you can refer to this article: Open Banking connection errors. It's a list of common errors you can encounter during the online bank connection process. It includes the troubleshooting steps on how you can deal with each of them.

I'll share this article with you as a reference: Understanding if you can connect your bank feeds to Open Banking. It's a list of online bank accounts that you can sync with your QBO company, along with others that are unavailable at this time.

Don't hesitate to post a reply if you have other questions about online banking in QBO. I'll be sure to get back to you.
