Unable to join Garden Ops match [PS4]

In Garden Ops, whenever my friend joins me, he gets disconnected with an error, telling him to check his internet connection even though its completely fine, so i though what if i join his match, so he created a lobby and he invites me, i joined and the game kicks me out within 5 seconds of me joining his match, telling me to check my internet connection as well even know its completely fine, though when me/ my friend joins a random public gardens ops game, that works fine, though sometime during the middle of some garden op match, the game kicks me telling me to check my internet connection, multiplayer works fine, this problem only applies to Garden Ops and only whenever i join a friend's Garden Ops game or when he joins my Garden Ops game
