For players who have this issue (CreateEndPoint: FailedToQueue: 4301) My issue was the same, I've tried several ways, updating my driver, my network, enable from NAT to Open. All does not work. End up the only solution that it works for me was, I was a LAN Cable user, switch your connection from LAN Ethernet > WiFI. I've tried this and it works! I can Host now or Join other players in the game.
P/S: But it is indeed weird that they disabled this options for LAN cable players, why just WiFi users can play the game?
