Temp Humid sensor error question

[mhinton]

Setup:
Arduino IDE 1.8.8
Seeeduino V4.2
Base Shield
Grove Temperature&Humidity Sensor

So i set this up as per the directions on the Temp and Humid webpage. However, I kept getting error message in the serial monitor that it could not read the sensor. "Read failFailed to read from DHT Humidity: 0.00 % Temperature: 0.00 *C"
To get it to work, I moved the sensor from D2 to I2C Grove Connector. Then changed the DHTPIN variable from 2 to 19. It works!
I went to reproduce the error with the original setup (D2 and DHTPIN=2). It worked the second time around. Any ideas as to what caused the original error ?
