I did reset to default via browser, ant3 panel and it try a few hours.
Than I did reset by clicking small button, like said in post nr 1.
Now I can't find ip of this antminer, guess it's the same vbut can't connect.
I use sniffer (i guess) to find ip deviaces and for other 2 ant3 miners I can find it.
In advance ty for any support.
