This site only allows 1 attachment, but I received a different error each time tried.  I attached the last error message I got. Maybe you can share these with your engineering team. 

The 1st error #15270 showed payroll update not complete because of missing file. 

The 2nd error #IC67305976 showed Internet Connection Error, server unavailable. 

The 3rd error #PS060 shows as QuickBooks Enhanced Payroll Service is not currently available.
