Sent 6 pings that remote has not responded to. 24/1/31

I used to be able to play happily, but from a certain point on, whenever I enter a room, a message saying "Sent 6 pings that remote has not responded to." appears and I get kicked out. I don't know if it's a bug, the server is weird, or just me, but I can't play at all anymore. I hope it improves soon.
