Up until 3 days ago I've had no issues with server disconnects or error messages and have been playing since launch. All of a sudden for the last 3 days I have been unable to complete a SINGLE game as I get the code:leaf and now code:net disconnected error exactly 4 minutes into every single game.
I've tried resetting modem/router, setting static/dynamic ip, using different servers including other international regions, restarting the app, restarting the system. My internet connection has not changed and remains fast and stable for all other online games. My general connection to the severs seems fine at around 50 ping and 0% packet loss.
My setup is:
PS4
Australia
Wired Connection
Hope this helps.
