Hi there, @Janice-Ryan.
Bank error 377 means QuickBooks Online (QBO) is unable to download transactions from your financial institution and requires you to update the connection with your bank.
You can log in and check your bank’s website for any alerts or notifications that could affect the connection. If there aren’t any, I recommend contacting our Live Support team so they can review the concern in more detail and help you move forward.
Here’s how:
- Go to the (?) Help icon in the top-right corner.
- Select the Search tab and enter a related topic.
- Click Contact Us.
- Provide a brief description of your concern and Continue.
- Choose between Chat with us or Have us call you as your preferred option.
You can check our support hours to see when assistance is available.
Feel free to leave a comment if you have additional questions about QBO. We’re happy to help.
