Hello @undeadwelder,
Welcome to the Community. I'm here to help you connect the bank account in QuickBooks Online.
There are several possible reasons why you're having trouble linking the account. You can perform some basic troubleshooting to isolate and fix the issue.
I recommend you start by logging into your bank's website and check if there are ongoing maintenance or messages that require your attention. Please note that some banks require you to enable third-party access first to link QuickBooks successfully.
Here's how:
- Log into your bank's website using the web browser.
-
Select User Profile.
3. Scroll-down to Password and Security.
4. Toggle "Third Party Access", then choose On.
5. Select Yes button to confirm.
If there are changes to the steps, please contact your bank. They'll be able to assist you further with enabling third-party access.
In case the problem persists, please let us know. You can leave a comment down below if you're getting a specific error code or message during the process.
