Switch 2 connection error - 3-ABGVA-0015

I keep getting this error on switch 2 when trying to play online. I’m stuck in the “loading…” screen for a while before the error message appears. “3-ABGVA-0015” “Session disconnected. You’ve lost connection to the dedicated server” I tried basically everything, reinstalling, signing in and out, rebooting device, switching internets, factory reset, etc. I tried both joining the game myself or in my friend’s party, both results in the same error. I also instantly get a “-0006” error when trying to join a party through matchmaking. No issues linking to microsoft account or getting the capes or playing offline. Tried in both docked and handheld mode.
