Greetings StonerSunshine,

I'm sorry to hear that you've been experiencing this issue with downloading the title on your Playstation 4 console. The error code CE-40868-6 appears to be specific to the console and my suggestion is to possibly contact Playstation Suppport for further assistance.
As it does seem to be connection related it appears you've done some basic network troubleshooting already, I'd also like to suggest the following:
- Ensure that "Cookies" and "Javascript" are enabled on the PSN browser. This can be done by opening the browser, pressing the options button then going into the "Settings" menu. Ensure that the options for both are checked, if they are you may refresh the setting by unchecking and rechecking them back on.

I hope this helps! Thanks for visiting the FINAL FANTASY XIV Technical Support Forums.
