My new S17+ gave me this message:    Socket connect failed: Connection refused

I checked the pool spelling then I flashed the SD card, and now my Miner Type is: Antminer X17. And Hardware Version   Socket connect failed: Connection refused

 In the kernel Log it seems I have a problem with a FAN. I changed every fan with a new fan.
