It's funny how the only option to problem solve available was 'ask the community'. Unfortunately the community are experiencing the same issue.

Hi Roxy15,

The QuickBooks Community is a great avenue to share your experiences while also learning from other users. Let me help you check your connection with your bank.

Bank feeds can be interrupted by maintenance on the bank's side, an issue with your bank account, or from us. A quick way to get more information about the behavior is to click Update on the Banking page. This will give you an error message or code that tells us what issues you're having.

1. Go to Bookkeeping and then Transactions,
2. Choose Banking.
3. Select Update.

You can follow the rest of the troubleshooting steps in this article: What to do if you get a bank error or can't download transactions in QuickBooks Online.

Feel free to reach back out if you need more help. You can mention the name of the bank and the error code or message you're receiving so we can check it on our end. We'll just be around to continue helping you.
