Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

The WV-33907-2 error code you are receiving is specific to the PS4. Usually, it's specifying that you are having trouble connecting to the Playstation Network. Your PS4 needs to connect to that first before it connects to the game server.

You mentioned you only receive that error sometimes. Do you receive any different error codes?

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
