I keep getting error code 216 while trying to load a multiplayer game

I haven’t played battlefront 2 in around 2 months. I have had issues with the game before but nothing like this. Basically I can open the game, ea will launch it and it will take me into the menu screen and it says I am connected. The problem emerges when I attempt to join an online match. When I try to go into any multiplayer game it connects me and finds me a game but while it’s loading and giving me the tips and it shows the planet screen(when it first starts playing the map specific music) it will just kick me. It also doesn’t show the loading thing in the bottom right. Then it puts me back into the main menu and says error code 216, check your connection and all that stuff. The thing is this problem is with no other game, my WiFi is fine, though not great but it’s not the problem, I’ve checked many things reset my computer did all that netsh reset/renew stuff in elevated cmd and stuff like that. Nothing works. Until I tried it without the firewall for a brief moment and it worked flawlessly. I thought I’d just found the solution, but little did I know that allowing battlefront through the firewall wasn’t enough. I need a way to play the game multiplayer with the firewall on, for safety, but all the things that say just go into firewall permissions and allow it, but that just doesn’t work. I tried for hours and I just don’t know, maybe it’s a problem with ea or smth. Please, anyone who knows anything about this, or can help me, I would very much appreciate it if you did. Thanks
