LMiC ABP example not working

End Devices (Nodes) LMIC

Hello. I am trying to test out the ABP example, but I get this in the serial monitor:
Starting
FAILURE
\Arduino\libraries\arduino-lmic-master\src\lmic\radio.c:689

I am using Arduino Uno R3 with Elecrow RFM95 Lora Shield.

Maybe the Pin mapping is not correct? I have no idea how to configure this:
// Pin mapping
const lmic_pinmap lmic_pins = {
.nss = 6,
.rxtx = LMIC_UNUSED_PIN,
.rst = 5,
.dio = {3, 4, LMIC_UNUSED_PIN},
};

Any help would be appreciated.

I think you should check and measure pin VCC in module Lora. VCC lora is 3.3V, so you must issues actually voltage in pin VCC.If you make sure that, you can change the following for testing:
+pin 3,4 by pin 2,3
+pin 6 by pin 10
