how do I correct error 163 when trying to connect with my bank?

Allow me to ensure you can connect your M&T Bank in QuickBooks Online (QBO), Fores.

The Bank error you encounter indicates that a website change has occurred, requiring an update of the financial institution's data to support the new site.  Furthermore, credential keys may have changed and need to be updated.

This can happen for a few reasons, such as:

• 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 is intermittently unavailable to access

Your first step is to check the M&T Bank website for any notifications about planned maintenance or system outages. Sometimes, the connection is down just temporarily.

If the issue persists, I recommend contacting our Live Support team to access your account securely and investigate the problem to restore your connection.

Here's how to connect with them:

1. Inside QuickBooks Online, navigate to the Help menu.
2. Select the Search option and type "contact support".
3. Choose the Contact Us tab at the bottom.
4. Enter the question, keyword, or topic you need help with.
5. Follow the prompts, then choose a way to connect with us.

Please note that support availability varies depending on your QBO plan.

In the meantime, you might consider manually uploading your bank transactions as a temporary solution.

Please feel free to respond with any questions or updates on your progress.
