"You have lost connection to the session" (Ps4)

I’ve been trying to connect to the game for about two weeks now and get this message everytime I try to connect to a match.

Does anyone else have this issue/have any idea on how to fix it?

Welcome to the Battlefield 4 experience. Enjoy your stay.
Do a hard reset of you router/modem/both and then try it again.

Uninstall and reinstall the game and updates.

ill give that a shot. thanks

no i ended up giving my ps4 a fixed IP address and putting it into a DMZ and that worked.
