Scuf no longer connects to the Ps4?

I haven't been able to log into the Ps4 with my Scuf Impact for days. When everything was still working, I connected the Scuf to my PC as a test. However, this did not work out. Every time I pressed the Ps button, a small Steam window opened. Then I tried to connect it to my Ps4 again and I really tried everything. I pressed the Share and Ps button together to establish a connection with the Ps4, but it didn't work. Then I pressed the reset button under the paddle and hung the Scuf with the cable on the Ps4. It all didn't work out. Now I can only get in with my steering wheel, but I can't play Fortnite.

I ask for any help on how to reconnect my controller.

Hard reset.

Forgot your playstation controller, or whatever it is called.
Hold that you have to reconnect.

Goes in the device settings of the ps
