Ps4 controller won't connect to console?

Tried to connect my Ps4 controller to my Ps4, but unfortunately that didn't work. My controller then looked up briefly in white and that was it. Even when you plugged the controller into the socket, there was only a brief orange glimpse. To cut a long story short: I've now got a new controller and it doesn't connect to my Ps4 via a cable…

In addition, the Ps4 is now also in safety mode…

Maybe one of you knows how I can help myself.

You could hold the share button and ps tastd at the same time and then with a keyboard or with the ps4 remote control the controller via bluetooth at> settings> devices> bluetooth connect… Or it would also have to go with the cable> connect the cable to ps4 and controller and then Hold down share key and ps key until it flashes again
