PS4 internet connection not possible?

I connected my PS4 to the Internet with a LAN cable. But I'm informed that the connection would have failed. Have the same LAN cable connected to my PC but everything works fine there. Can anyone help me

Restart Ps 4
If that doesn't help restart router
If that doesn't help, contact support

Do you have Wi-Fi on your cell phone and other devices?

I'm not familiar with PS4, but can you manually set the IP address or via DHCP? Maybe there's the mistake?!

Yep I have. On the PS4 I'm in there via LAN cable. I plugged the same LAN cable into my PC and the internet works there.
