I appreciate you chiming in on this thread and posting your concern, @dneilsen71.

I'd also feel the same when my bank gets disconnected daily and suddenly reconnects again. Rest assured, I’m here to help and will address your concern about your bank connection. 

There are several possible causes for your QBSE bank accounts to lose connection. Among these are:

• The bank is having system maintenance. 
• Log-in credentials set up in QBSE don't match with the online banking login.
• QBSE is unable to connect to your bank's website.

We can click on Refresh All multiple times on your Banking page. This way, your bank refreshes the connection between your financial institution and the QBSE. 

Please see this sample screenshot below for reference:

If the same thing happens, I recommend following the basic troubleshooting steps provided by my colleague above to sort out this issue. 

Also, did you encounter any error messages when your bank disconnects? Any additional information will get us closer to a resolution.

Once your bank account is connected, you can categorize the transactions to ensure your financial records are correct. For more guidance, feel free to check out this article for future reference: Categorize transactions in QuickBooks Self-Employed.

Get back to me here if you have further questions about bank connections in QBSE. Tag me in your reply, and I’ll sprint back into action. Have a good one, and keep safe.
