Do you have it disconnected from the Internet when you are attempting these setting changes?
Do you have ports forwarded in your router for remote viewing, when it's working normally?

1.- It's connected to the internet but I tried to factory reset it many times while i disconnected the cable.
2. Yes i have ports for remote viewing , i use Hik connect.
