Hello, @stephen6.
Let's ensure you'll be able to connect you PayPal account successfully.
You may need to use/enter the bank's URL to connect your account. To connect the correct bank account, log in to your bank's website to copy and then paste the URL in the Connect an account page. Once completed, follow the on-screen instructions until you'll be able to connect your bank account to QuickBooks successfully.
However, if the problem continues, I recommend getting in touch with our Support Team to check and investigate this further securely.
In addition, you can also check these articles for more details about connecting bank/credit card accounts:
Keep posted if you have any other banking questions, I'll be right here to help. Have a great day ahead!
