This is a thread about connecting to other players, not AI.
I think you also are mistaking the simspeed slowdown for the connection issue that this thread is about.

Can I just add my two cents here, I have also experienced this, especially so in the last 2 patches. To the point when I host my own game now, with AIX only, my game crawls.

Two players I know in the same house connecting through FAF get the same issue with proxy connections. Close and open FAF a few times and you get a chance that 1-10 will connect correctly.

The negotiation is a little too sensitive, would be great if there was several connection reattempts in place before the proxy kicks in at the very least.

Once you are connected to the game, it send a "connected" message to the server, that avoid any proxy connection in the future.

Maybe there is a bug, but your log doesn't prove it

I would need :
- game.log
- faforever.log
- from BOTH players.

Also, not in here, in the tech forum.

ZEP, I would like to provide you proof that there is a bug, but not sure how I would prove it.
We've had countless games with know (good connection players), then suddenly there is an issue where we must go through the proxy. Reconnections will not help this, however joining a different game generally will. A workaround we've found, which is less the ideal, is to get everyone to x up, reconnect one of the proxied people and launch before the proxy has a chance to kick in.

I have an example, of a game.log, attached, which I think is an example of such case. However I don't think this is the proof you are going to accept.

Would it be better with Wireshark logs, or telnet sessions using FA ports to and from each player? However then we need to reproduce in a game when it's not connecting correctly. (Or at least staying connected properly).

You also see the USE PROXY message after the Connecting... in the chat. (unless Xinnony removed it).

Normally you can see in the lobby if "Connecting to XXXX..." comes up twice

Short answer : No.

I have 0 proof of a bug.

Sorry to repost some of this info from another thread. I'm 99.9% sure the proxy code has a bug that is forcing the proxy with connections that still work. We are seeing this a lot over the last few months. I've had a look at the client side code and can't see the bug, does there server side make any decisions?
If I alter the proxy code to ignore proxy for AU to AU connections would there be any chance of it being accepted?

Well over the last two or so weeks the proxy is kicking in way more often then it even did. I'm convinced some code change has made it more sensitive. Please help us Aussies, we can't afford to go through the proxy. The world hates us as it is.

You don't need to know the details, it will takes too much time to explain, and you don't really need to know.

The server has multiple ways to know if a possible will be possible or not, and don't worry, the decision is based on a lap of time bigger than 500 ms.

Pings are unrelated, and FA send nothing to the server.

The server is smart enough to know that if 15 seconds after sending a connection request, no connection is done, there is a problem.

You don't remember a lot of connection problems because :

- failed attempts were more subtle (no proxy message).
- less players (and way less new players).
- no ipv6 that is incompatible with FA.

But it doesn't take 15 seconds... I've had plenty of games where I've gone from clicking the game to join it in the lobby, to readied up with all players connected in <5s, with several of those players connected via the proxy (I know they were connected via the proxy because after the game finishes I have the 'Trouble connecting' message pop up. So if I went from clicking to join a game to game launch in around 10s, clearly it's not waiting 15s for the proxy to attempt a connection... I think you should up the time to 30s purely by means of an experiment, to prove all we naysayers wrong. If connection reliability improves... Well, god knows, but something isn't right.

Also a small point - How does the FAF server KNOW that connection has been unsuccessful if no data is sent from either client to tell it?

I too am sceptical of how this all works. As far as I understand it, the game engine first attempts to connect each player directly to every other player. If and only if this has failed will it then attempt to connect the problematic players to each other via a central server (The proxy). This will always work because if the clients are both connected to the FAF Lobby server, they are also capable of connecting to the proxy.

This is where the problem comes in. To my mind, somewhere the game engine has to send a command to the FAF server saying that the P2P connection is not working as expected, so that the FAF server knows to attempt a proxy connection. But what if the ping between the client and the FAF server is so large (As it would be from Australia to Europe) that in the time it takes for that signal to arrive, the connection has succeeded?

How long does the system give between having the two clients meet, and deciding that they need the proxy? 10ms? 100? 5000? I am in Aberdeen with a flawless connection, and I have been connected using the proxy to people in Germany, and I'm willing to bet any money that if the connection were given a 30 second window before the proxy system kicks in, we'd get a successful connection. This problem will be even worse for people down under, I mean, the Australians could all connect totally fine in GPGnet days, and I certainly don't remember as many connection problems back then as we have now.

What would happen if the time given for the P2P non-proxy connection to complete were increased?
