My antminer s3+ was running well. There was a power cut. When power came in I started my antminer. The red led blinked for 10 to 15 seconds then it turned off. The two leds (green and orange) of ethernet port are off. I directly connected the ethernet cable to my pc and tried to log into config page. But I could not log in. I got an error message
. Can you please help me. Thank you.
