I cannot reconnect nationwide bank. i have removed it, deleted cookies. now it is says "sorry cannot process your request at this time" Its been doing this over a week.

The Nationwide bank should be available for open banking connection, @keirconway1.

To isolate the issue, you can start by connecting the account using another supported browser. If that doesn't make any difference, I would suggest contacting our Support Team to investigate this further.

To contact support:

1. Sign in to your QuickBooks account.
2. Select the Help (?) icon.
3. Scroll down to select the Contact Us button and follow the prompts.
4. You will be able to request a callback or start a live chat with an expert.

Refer to this article for more details: How to get help with QuickBooks.
