A 5th transaction and same issue. 
But 4 transactions in a row? Between the 1st two was about 11 hour gap. Then about a 12 hour gap between 2nd and 3rd. Then a 5 minute gap between 3rd and 4th.
Do you have checked if the system time of your computer is currently on the accurate time?
Yes it is. It's set for automatic update using ntp server.
