Xbox one cant sign in or add profile

Uhh that didn't work either

Thanks for the help but unfortunately I was still unable to add my account

You can try resetting your Xbox One's network settings. Go to network settings on the console and select "Reset network settings." Please note that this will erase all network settings and you will need to configure the connection again.

Unfortunately,this haven't worked.
