Hey man,
I have problems with ps4remotepkgsender (on pc) and remote pkg installer (on ps4). Sometimes ago, I could send pkg from pc to ps4 just fine. But today sony servers take control of the pkgs which are being sent over local network. Normally, ps4remotepkgsender sends download command to ps4 with chosen pkg and it will be installed properly on ps4, now it sends the file only around 30-40% then suddenly stops, there's no network activity of the ps4remotepkgsender (on pc's task manager), but on ps4, the game is still downloading from sony servers when I check (original fpkg is ~4GB but on download notification, it's ~7GB which I'm pretty sure it is being downloaded from sony.
To fix that, I reconfigured network by adding al azip dns servers to DNS1 and 2 on network settings, everything is working properly now.
But I have some questions, why it happens now but not before? Do you know something has changed?
And before adding al azif dns to fix that, I tried to use mac filter on my router but the ps4 couldn't receive download command from ps4remotepkgsender, I thought after being filtered by mac address, the Ps4 should be able to connect to local network but not the internet. Therefore pkg remote installer should work as usual.
