NFS Unbound - error code DR1001 "You have been disconnected from the session"

PC Player here.

Bought the game from Epic.
Since the day before volume 6, I couldn't stop getting this message every time I want to join a server mid-way through loading, then the game gets stuck on loading. Now, it still happens, and ONLY VERY RARELY I actually get to join a server or PVP Races. Unfortunately this error happens WAY TOO OFTEN AND I'm slowly contemplating whether this game is actually broken or the servers are. I always have to ALT F4 the game and reopen again, just to get the same bloody message. I have good internet, I've uninstalled and repaired this game countless times, and also cleared EA App's cache. I even signed out and reinstalled EA AND UNBOUND COMPLETELY just to find out I managed to join a server once, before completely getting KICKED OUT AGAIN. I really need help in this, I just got back to convincing myself to play this again, and this is almost the nail to the coffin for me.
