Bank account was connected no problem and now it won’t let me reconnect. It’s says ‘success’ but then it tells me there’s still a problem, any ideas?

Hi there, @jackie_stewart. 

Thank you for posting to the Community. 

I would love to help you, but I need some extra details about your concern. This way, I'll be able to provide you an accurate solution. What bank are you using to verify if there are any related issues with it? Did you encounter any error codes?  I would also appreciate if you can provide me additional information about the error you've experience.

If Yes, you can check these articles: Fix bank errors in QuickBooks Online, Fix banking error 106, Fix banking error 323, Fix banking error 101, Fix Banking Error 155, Fix banking error 109, Fix banking error 192, Fix banking error 102 and 105. 

As a workaround, you can manually upload the transaction into QuickBooks. 

Any additional information is greatly appreciated. I'm looking forward to your reply.
