D4 is GPIO02 which is the LEDBUILTIN on NodeMCU. Maybe this is causing the problem, because it is used for Status blinking during startup. Try commenting out digital read & write:

void tick() {
  //toggle state
  //uint16_t state = digitalRead(LED_BUILTIN);  // get the current state of GPIO1 pin
  //digitalWrite(LED_BUILTIN, !state);     // set pin to the opposite state
}
