4th friend can’t join zombies private lobby.

[Derkton]

Every time my 4th friend joins (whoever joins last, it’s not one friend it happens to) they get an error saying the lobby isn’t open. We are playing with two couples and have two LANs (2 people are on one LAN and the other two are on the same LAN as well) any advice?

You basically found out the problem.
2 players on the same LAN.
Can be solved if the 2nd player on that LAN uses mobile data or gets on VPN.
The game still needs polishing, but it's working.

02l that doesn’t make much sense, how can one person from the same Lan join but the moment two people join it doesn’t work

[ljave018]

Derkton probably because of the same IP address used to log in.
I'd advise you to try with any VPN, or use mobile data for the second player, until that gets resolved.
