I'm playing an online game on a Chinese server, and I sometimes get disconnected when the VPN gets congested. When this happens, I have to restart the game and re-enter the map, while the rest of my group is probably wondering what I'm doing.
How do I explain to my group that I got disconnected from the server?
I've also seen people complain use 卡 to complain that they're lagging, but I guess it could just as well refer to being stuck. Is there a less ambiguous way to refer to network lag?
