there are a number of variables in a connection.
1 the service
2 the region settings for steam (make sure they are the same and in the correct area of the world)
3 the firewalls being configured incorrectly

just to name the top 3 possible reasons for the issue.

Pretty sure the connections are peer to peer, so one or both of you, in party members have crappy internet.

We are in the same room with two computers, steam locale is no problem, I check the firewall, thank you
What strange not to increase LAN, experience would be much better

We are in the same room with two computers，Wonder why they don't do LAN mode

low ram or low cpu on host computer.

16G ram GTX960 CPU I7 4790K ，I don't think that is a problem of configuration

And was this computer hosting? And weren't they running xyz processes in the background while hosting? I found out that when i terminate my other processes I can host the game, otherwise players disconnect all the time (and its not my internet connection).

Problem is not the same as you described, he is uncertainty, sometimes 1 hour all right, sometimes 5 minutes break, according to the Chinese players this way the result of the discussion, as if the server's problem, because if two people are online will not broken through the VPN

Fix for "Failed to Connect" message
This game requires unusual outbound UDP traffic that many firewalls will drop. Some users are familiar with games that require "port forwarding" an internet facing connection through their firewall to an internal host- this is called NAT outside of the realm of home user network gear.

This game required a bit more than that to get working.

Here is what i did to resolve the issue - the steps will probably be different for you depending on your network topology.

First i had to open a live log viewer for my firewall and record the drop table events the game was generating. In order for this game to work you need to allow the following ports from yout internal network out to the following public IP blocks.

UDP 514, 5001, 6001
destination network 193.59.178.0/24 -this appears to be GOG network
destination host 194.110.240.185 -this is registered as a business IP is Poland

Also some gen4 firewalls can beconfigured to drop traffic based on geoip tagging- mine was

I had to allow outbound connection for this traffic to bypass my drop rules for all traffic to or from poland

port UDP 514 is a reserved port for syslog and many firewalls even home firewalls will drop low range UDP ports as suspicious when traversing into an internet zone - you may have issues with this

-i would like an explanation from the dev team why this is used

I hope this helps others with getting the game working.

good luck

but i fact this result in canging my router cfg for that game :/
