Hi there, otraroadside.

I understand how you feel when errors occur seemingly out of the blue, especially when you haven't made any changes to your company file information.

While it may seem puzzling, there can be various reasons behind these issues. Sometimes, system changes can inadvertently affect the stability of certain features. Additionally, there could be underlying factors within the software itself that occasionally lead to these errors.

Since the above responses already provided the things that I can suggest here, I recommend reaching out to the QB Desktop Payroll Support to investigate further and provide you with a more specific explanation for the recurring Payroll Service Connection Error you've been experiencing. They are open from 6 AM to 6 PM PT.

If you have other questions in mind, feel free to go back to this thread. Take care and have a  good one!
