[0.11.21] Multiplayer works only for two players

[ivosh]

Hello,

Only host remains in the game (second player is kicked) when the third one tries to connect. Order of connecting players does not matter.
Following process reproduces the problem.

1) I host the game.
2) Any player successfully connects and enters the game.
3) Second players tries to connect, but no save is transferred, first player leaves instead and third player 'does not respond'.
4) After waiting for the third player to respond expires, host can still play the game, one player can successfully connect again (but only the first one).

There is a time gap between two players connecting, so two players never connects at the same time.

We have always played the game in two players, so I'm not sure if this bug appeared in version 0.11.21 or exists for longer time.

We play without any mods, free game, two players on linux (including host) and one on windows.

Will need more details, like all your setups, log files, how the game is hosted/players connect(wifi/lan), because this is certainly not an 11.21 problem.

We are playing with 3 people withtout problems, all have an extern IP. We tried this with 2 people playing in the same lan network and one from the outiside, the third player cant connect. guess this is the same setup

[ivosh]

We play over Internet, my router has public IP, default factorio port forwarded to my machine, which is connected through wifi. One player is connected through cable to the Internet, other one through wifi.

See the attached file for log, please.

This is a known problem -- if one of the players is playing through the internet, then all have to connect to the internet addresses. There are some details here: https://forums.factorio.com/forum/vie ... =10#p65674

In your case the other local player has to connect using the router IP address as well.

Both other players connect to host internet address, so I think this is not the same case as bug reported before.

I played a LAN game with 2 other players, a couple of weeks ago. I think it was 11.19. It worked superbly, once I set the "delay" thingie to a very low value (33ms I think). Nobody got disconnected, and we played for hours and hours.

Okay, I will try to set lower delay and see if it will help, but as I said, we do not play over LAN, but over the Internet (all of us).

[ivosh]

We tryed to play with latency setting without success. I tryed with different players from different locations, using wired connection over the Internet (not LAN) to me.
