Weird issue trying to connect to server

I'm trying to see if it's just an issue on my end, but I'm having trouble connecting to the server. I load into the lobby, everything is still loading and it's laggy, and if I back out to the main menu it's telling me I'm having connection issues and prompting me to retry. I've recently upgraded my router, I've tried resetting it, and I've tried restarting my PS5 and even closing the game. After a couple of tries it will let me in, then start acting up again after a few matches.
