Hello there, Jeanie.
There are several common reasons why banks disconnect in QuickBooks. Below are the most common causes that can disrupt the connection:
- Bank website updates or maintenance
- Password and bank credential changes
- Security settings at the bank
- Using autofill or copy/paste
- Multiple QuickBooks connections to the same bank
- Bank-side connection issues
To help you sort this out, could you please let me know if you received a specific error code when the connection broke? Also, which bank are you using for your QuickBooks connection? Knowing this information would allow us to provide more tailored assistance.
Please don't hesitate to comment below if you have any other questions.
