Hi there, @peter-wyro.
I'm here to help you connect your bank account to QuickBooks Online (QBO).
As of now, you can use the bank's URL to ensure you're using the correct link when connecting the bank.
You can also check this article to learn more about connecting bank/credit card accounts to QBO: Connect bank and credit card accounts to QuickBooks Online.
However, if the problem continues, I suggest getting in touch with our Support Team to check and investigate this further securely.
For the support's contact information, you can check it here: Contact the QuickBooks Online Customer Support team.
Keep in touch if you have any other banking questions, I'm just a few clicks away to help. Have a good day ahead!
