The child played with the modem, and now the internet connection is intermittent, which is why there's no Conflux. As for the mission, it seems the developers made another mistake. I replayed it, and everything was fine, but the "Choice" quest didn't appear at all, and the gate that was closed last time was open. Also, if you take the second blood upgrade in the first mission, this glitch will occur, but if you don't take it, everything is normal, but the "Choice" quest is still missing.
