Hi there, @fourpeaksminingc,
Your bank connection with QuickBooks may be interrupted for any of the following reasons:
Let's log in to your bank's website to see if their server is working properly, and isn't under system maintenance. This could be the reason why the auto-update has stopped working.
If everything works fine on their end, you can manually update your bank feeds. This is to download transactions that have cleared your bank.
If there's a need to change your credentials on your financial institution, check this out: How to update your Bank Account Sign-in Information. This article provides detailed steps on how to edit your data to re-establish the connection.
You can import transactions using a .CSV file. if the issue persists. This way, you'll be able to bring them in to QBO.
I'd also appreciate if you can add which bank you're currently working on. This will help me provide accurate information about your concern for today.
Keep me posted on how this goes and I'll get back to you.
