I was having the same problem. In QuickBooks Time, at the top, I clicked on the "QB QuickBooks" symbol and it brought up the option to "Clear Company File Path" clicked on that with my QuickBooks company file open and cleared the path. Went to my QuickBooks company, under the App Management, update Web Services and it reconnected and sent all my information over. After weeks of messing with this, I hope this helps someone else too.
