I've been experiencing constant connection issues since March 28th. The error codes are as follows:Error Code: 0Error Code: 4Error Code: CSF  

When I do manage to connect, I get kicked out or fail to load when trying to join a PvP match. Additionally, I'm encountering problems after exiting the lobby following a match. Prior to this date, there were no issues with authentication or connecting to the game.
I have ruled out any connectivity issues on my end. There have also been no changes to the operating system—no new software installations or critical updates were made.
