Autostart remote car starter not working

The Autostart remote starter is not working.
Everything else works. The unlock door, unlock trunk, lock door all work well. But the remote start doesnt work. I will hear a click when it tries to start the car but then nothing,
Seem like something is missing or disconnected.

Note that usually there’s a flashing blue light. Its not the case anymore. There is no more light on the antenna.
I have tested all the fuses in the trunk and underneath the steering wheel and theyre all working.

The car is a subaru outback, if anyone have some tricks i can try,

Thank you,
