Continuously disconnected from Battlefield V's EA Servers (PS4)

Get disconnected from the EA Servers every time I try play any of the Firestorm modes, but yet I can play any of the multiplayer modes without an issue. I've reset all my connections multiple times, I have a very low ping and I've restarted both my PS4 and modem multiple times. I have a static connection from the PlayStation to the modem, all the ports EA require are open and my PS4 is in the DMZ.

Can any one help? I'm going to completely miss out on all of this week's Trial by Fire challenges, never mind the reward, if this continues.
