This happened during an online multiplayer Civ 6 game. There were 7 players. Another player and I were about to begin a war, and I sent a joint war against an enemy civ. After I sent the trade request, all of the other 6 players supposedly left at once, and I was spammed with the 'All Alone' notification. Although this sounds like a network issue, I am confused, because I had an unrelated download going on which did not stop or slow down. I'm quite interested what this might be. Is this something that has happened before, or was it a simple internet issue.
