Great job for following the steps on how to reconnect your bank in QuickBooks Online.
Let's perform other troubleshooting steps by logging in to the bank's website through QuickBooks. The issue may be on their end and that's why you're unable to reconnect your financial institution (FI).
To do so, please follow the steps listed below for your guidance:
Go to Banking from the left navigation bar.
Click Add account.
Search your bank and click it.
Copy the URL and paste it on the other tab.
Then, sign in using your bank's username and password.
When you're able to sign in, you're halfway there. Check for any messages, notifications, or alerts. Any display can potentially block QuickBooks from connecting and downloading transactions.
If you make changes on their website, you also need to update QuickBooks as well. This will help the system to recognize the information easily when reconnecting your FI.
Here's how to update your account in QuickBooks:
Go back to the Banking page.
Select your bank, then click the pencil icon to edit.
Select Edit sign-in info.
Enter the new Login and Password info, then click Saveandconnect.
Also, errors can block QuickBooks from syncing your bank. Follow these links below on how to fix them:
