Cannot connect to router

So I’ve been having some connectivity issues today and I have connected to the router like 3 or four times through winbox.
But now whenever I try to connect It just says
ERROR: could not connect to [MAC]
also the ip is 0.0.0.0
I try to hard reset but nothing happens.

If you factory reset it with the reset button for 5 seconds at power on, you should be able to connect to 192.168.88.1 with telnet or ssh using user admin and no password.

I already fixed it. The problem was sometimes instead of [the light] first flashing and the turning off when I press and holded the button it turned off and then around 10 seconds later it flashed rapidly twice and nothing else
