I was playing my PS4 two days ago and then packed it up with two controllers that were both connected to this PS4.
I got to where I was going, set everything up and now the controllers won't connect. They show pulsing orange when they plug in, but when I hit the PS Button to connect, it blinks white 1-2 times and goes back to orange.
I've had this problem a couple of times in the last year, and the following steps fixed my problem each time. I tried resetting controllers, PS4 database, and all the usual steps people suggest in this thread and others.
If possible, use voice or another controller to turn on the PS4, and power it down completely (not rest mode)
Unplug PS4 for 2-3 minutes
Plug PS4 back in
Attempt to turn on using the controller that wouldn't connect. It should now work fine
Hold the PS-button and Share-button simultanously for some seconds while the PS4 is turned on. This will reset all connections of the controller and searches for a new one. If this doesn't help, try different USB-cables after resetting. If that also doesnt work, your controller is probably damaged.
If you have another controller go in devices > bluetooth and delete all controllers except on with green dot by it and then press ps button and share button on controller that won't connect it will show up in bluetooth devices
I had this same problem. My best possible answer is shutting down your game and pulling out the power cord from the ps4 and give it a about a half of an hour. Then you plug it back in then connect your controller with USB and it should be working properly .
Pressing and holding the PS Home button and share button did it for me. While I had the system in rest mode and charge cable connected. This was because I had to turn the system on manually and without communication between the pair the system fell asleep
Even after pushing the reset button behind the controller. Then sure enough, they found a connection and the system ran an update.
