On the approach LOC 30. Established on the approach leveling at 2;100 feet 1.2 miles from FAF we got a GPWS warning. We did everything to procedures. No cause. CA (Captain) was PF (Pilot Flying.) We did a go around and circled back to do the same approach without any problem. Tower gave us a number to follow up. The CA called them. Tower said that's the 2nd time the GPWS warnings has been a problem on that approach. Then the CA went on to explain what GPWS is to the tower controllers.
