Can't connect to most players

[realatlas]

Okay, first of all: Yes, I did use the search function. If my problem already appeared and got solved, I am sorry and will be thankful for showing me that thread.

I got bad connection issues in three different cases:

Case 1: can't connect at all to a game. I just can't join it. After i double clicked on the game in FAF, FA starts, but all i see is a black screen. The little window saying "trying to connect" or whatever just doessn't appear. Thats the worst. Happens with nearly every third game.

Case 2: I can connect to the game. But in the middle of the game i lose connection to ONE player. For some seconds i see that counting-up, then it stops again, but the game freezes. Looking at networkstats it says that that player got a bottleneck ack. But all other players still got connection to him/her, it's only me who hasn't. Had that quite a few times now, it's annoying, especcially for my game mates.

Case 3: I can connect to the game and play without troubles. But after the game is over, it says that i couldn't connect to some players; only via proxy.

In all 3 cases that window looks like that:

I looked up that wiki page for connection troubles and tried everything possible.

Of course I opened that UPD port 6112. And I tried UPNP. DMZ is not possible, my router is not able to do that.
I turned off my firewall, even my antivirus programme. Nothing changed.
I'm desperate.

Any suggestions?

And by the way: Where do I find game.log? It's not in that folder..

Try with Ethernet cable.

hey man. did you ever figure this out? im having the black screen problem and struggling to connect to people :/

[realatlas]

No... i just had case 2 again. It sucks so much. I don't have any problems with my internet connection at all, it's only in troubles with FAF. After i left the game right now, it said that i was connected via proxy to every single player. How can that be? Seriously??

Firewall/Router issues. Check the wiki about connection problems.

Wow, i got some news.

I just downloaded 2 port-checking programmes and both say UPD port 6112 is closed. I have NO idea why.
I disabled my windows firefall, shutted down my antivirus programme. And yes, i enabled port forwarding for UDP 6112 at my router settings.
But it still says "Your port is not open or not reachable!".

I hope I will find out where this fucking shit comes from .... i'll let you know.

A port can't be opened if there is no program that listen to it.

How do i make the port listen to FA? In FAF, menu Set Game Port I chose 6112, too: http://puu.sh/5JIp0

This is my router configuration: http://puu.sh/5JImf

And i even tried an exception rule at the firewall settings: http://puu.sh/5JIv7
I also set the game path for the FA.exe here, too.

What else to do?
