The error code 163 indicates that your financial institution's data has changed a website and needs an update, Mark.
This usually occurs when:
- A financial institution switches its Internet service provider
- If an incorrect login link or site is used
- The bank website is down for scheduled maintenance or intermittently unavailable to access
To verify, contact your bank institution and ask them if they've switched to a different internet service provider or if there's a scheduled maintenance.
If they've switched to a different internet service or you've used an incorrect login link, we can re-enter your sign-in information for your bank account.
- In the left navigation panel, click the Transactions tab and select Bank Transactions.
- Select the bank account that isn't connecting and click the Pencil icon.
- Click on Edit sign-in info.
- Then, re-enter your sign-in information for your bank account.
- Once done, save the information and update the bank to download new transactions.
Alternatively, we can update your Bank Transaction page using other supported browser
to optimize QuickBooks Online (QBO) performance.
If the issue persists, please contact our QuickBooks Online phone support team. They have the necessary tools and expertise to investigate the cause of this issue.
