What reset factory did you do? Did you reset it through webGUI?
Try to hard reset the miner using IP/reset button that you can find in the front of the miner.
Here is the image below.

Now, configure it again and try
Sigma pool or try
kano.is pool and let's see if it works.
Hello
Thanks for the reply
Yes, I did factory Reset through the webGUI.
Your method also did not work. Hold IP/reset 15 Sec but not hard reset
The miner works fine, but I can not change the pool address!
