An unknown error has occurred message

KingOfBadRNG

I've recently got a new ps4 with a built in terabyte

I've been trying to play with friends and I keep getting an issue saying an unknown error has occurred which i need to close app and join a friends party for it to work 1 third of a time.

By joining a friends party then all ready up

1 third of the time.

I'm not sure its my ps4 model being recent but this bug have been happening for several months.
