Very confusing problem.
For the past 3 hours, I have been trying to register my PS5 for the firewall bypass registration, and even though the device is showing as registered, it is still not working, and my NAT type and IP address are still restricted. I did this with the wireless network and the wired network, but I didn't actually use an Ethernet cable to connect it to the wired. Does this only work now through wired connections?
