I've had a similar one.

For my part i could play until yesterday. Some problems of connections as the others says (bots, deconnection messages, NAT failure, etc...) but today i do not get any possibility to Pantheon: the game keeps telling me it didn't find any suitable match and i get the other message "not complete" but no more connection info. My ports are open. I'm in Norway and use a 4 MB line, my router is configured as my firewall, as yesterday.

Did something was changed since yesterday? I can't say from the forums threads...

I'm used to Networks issues and i can't say it's something on my side. Maybe too few Europeans players? From the explanations of Frog i was expecting less problems after the start but no i can't play multiplayer at all.

I'm an average player and i think this is going to be quite frustrating for a lot of people that just want to have some fun, not wait and get frustrated to "maybe" join a play... The most interesting part is the multiplayer part and you get bots in multiplayer. Hopefully this is going to vanish soon.

At that point i'll be surely some others getting back to other games that actually works without need to have a degree in Network Administration and i'll take a look in a couple of week, hoping that the technicians found a way to help us enjoy this game. 

i think frog needs to take 5 or so people haveing problems host a game and try and get them in it and see whats causeing the problems.

Also could it be others causeing the problems for us? i can conc to say 4 of 5 people then the 5th person does nothing, is that me or him? am i just unlucky always getting these people? what about when i conc to 3 people game goes with us 4 then 2-3 of them all drop as the game loads? is that me? possably them? or a problem with the nat thing?

First, here is my setup.  I have a speedstream dsl modem (on AT&T/sbcglobal) which is configured as a DSL bridge.  Basically this means it's completely invisible to TCP/IP, it just passes ethernet traffic to the DSLAM at the central office.  I have to use PPPOE to access the Internet which means my packet size is 1492, not 1500 which is the normal ethernet packet size (I note this because I wonder if this might be factor in connections -- this affects MTU, MSS and packet fragmentation for everyone that has to use this).

For TCP/IP routing I have a Linksys WRT54GS running Tomato firmware (http://www.polarcloud.com/firmware).  This is basically a linux distribution that runs on the WRT Linksys routers.  The system I use to play games is wired directly to this router. UPNP is disabled on my router.

I have ports 6100-6200 UDP and 6073 UDP set for passthrough directly to my game system.  If I fire up a small application that listens on those ports and use nmap on a remote server to scan my IP, they are wide open.  If I use portforward.com's PFPortChecker app, it also concurs those ports are wide open to the Internet.  So I'm very confident my router is passing traffic as expected.  The problems described going forward happen irregardless of whether I use the ImpulseReactorOptions binary to set the ports manually or just let it do it's thing.  I get the same exact results.

When I try to play multiplayer I can get as far as the connection window.  If I click on this it brings up the window that is supposed to show details of who I am connecting with, however at this point it is completely empty.  It takes roughly 5 to 10 minutes before I even see any information in this window.  Invariably, it will say that I, and a few other people, have not connected to anyone yet.  All the other players have no status at all.  So basically it either says not connected to anyone, or it just says their name.  If I wait it out, eventually everyone drops out or I get tired of waiting and go do something else.

Oddly, one single time before this last patch I actually got into a pantheon game.   In that particular instance, there was 0 delay in joining and creating the game.  Meaning, I clicked "Fight!" and it was about 10 seconds and the game instantly started.  I have never had that happen ever again or been able to play a multiplayer game after that.

This is as much information as I can think to give so if you want more, feel free to ask.  It would probably help a whole lot if there was some kind of networking debug mode that would log exactly what the program was trying to do and what exactly was failing.

As an aside, I find it hard to believe that this could be the fault of anyone's router if they are truly setting up the router for passthrough as Monk described in his guide.  NAT is very old and very well tried and true these days.  While I concede that there might be a buggy implementation here or there, I find it very hard to believe that the vast majority of routers have any sort of issue with this very well established technology, especially popular and common routers like Linksys, Dlink and Netgear.  This is not to say that those company's products are perfect, but they have plenty enough market saturation that if there was a major NAT issue every person with one of those products would be having trouble with many more things than Demigod.

Most often it is just connections to people sometimes work, most often dont and say 'connection to xyz has failed'. All relevant ports are open on all parties. We have checked with the portforward.com checker.

Problems with custom game lobby taking ages to refresh sometimes, i guess thats server load on your side, adds to the frustration.

Games sometimes come back instantly as failed to join, i assume they are dead games which the lobby is not removing from the list...??

Sometimes when you even have everyone in the game lobby, there will be someone who has not connected to someone else and the game will not launch until that is resolved (by kicking them and getting them to rejoin).

I get "Failed to get game info" when I want to play Pantheon, although my game is up to date

Hopefully you're aware of my issue (seen as you posted!) but  for arguements sake....

Problem is as follows.

I have a direct connection to my cable modem, VirginMedia ISP, no firewalls present. Download speed of 9.2Mb/s, Upload of 0.4Mb/s.

Matchmaking works fine, barring the typical errors (0ms pings, connection problems etc). Upon launching the game loads fine (get passed the "connecting to other players" window, and loading screen) however as soon as the game loads one of two things occur.

1) Game begins to lag horribly, resulting in a disconnect.

2) Game instantly disconnects on load, resulting in a flood of "A player has left the game" because i've been the one who has disconnected.

I've only experienced this error (even then intermitently) on Games 4v4 or 5v5, 3v3 seems to have no issue with it.

Bump.  This post needs a sticky.  I think most people miss it.

My issue is, i can't ever get into a game lobby when someone else is hosting. Sometimes i get connected to one or 2 people and they can connect to me. Mostly i can't connect to anyone. I'm absolutely positive its not a port fowarding thing for me.

When i host some players can get to the lobby but mostly only ones that oddly say not connected to anyone but it shows me connected to them.

skirmish Pan=Can't ever join any of them.

I have qwest adsl 7.0

i use a actiontec GT701wg

Vista 32 home premium.

Port forwarded on a dmz.

I have no NAT options besides on and off.

I have updated firm ware power cycled. Setup static ips dynamic ips. Used ipv4 and 6

No firewalls in windows or enabled in my router.

So far in retail I havent been able to connect to a single multiplayer match. The ports are open in the router and verified via grc.com to be open. In the connection info log at the bottom right it often shows me that ive either successfully connected to one person or am attempting to connect to people and everyone else is listed as either waiting to connect or havent connected. If I wait long enough it will say I have disconnected from the NAT facilitator.

Wow, if you say you thought it works perfectly then we're going to have problems lol. I thought you were still in emergency mode it's so bad.

-Every 15 minutes to an hour, I get disconnected from the NAT Facilitator. If this happens while I'm connecting to a game, the connection status box will disappear and I think I've failed completely and must quit, so I do. I'm not sure if that's what I'm supposed to do, but that's what it feels like. Sometimes this happens in the middle of the game but it does not seem to ruin all games.

-Sometimes games that do not need a password will ask for a password.

-Almost every game, without fail, will have someone drop due to connection failure before the game starts, which usually results in the rest of the team quitting.

-Sometimes when joining or doing a pantheon, the game says I'm connected to everyone and yet the game will not let me in the lobby, so I have to cancel anyway after having waited 5 minutes to connect.

-90% of the games I try to join just give me "failed to join game" or something right off the bat. Friends of mine will have games with room to spare, and I will not be able to enter. I have had hosts abandon otherwise perfectly good lobbies because their friends could not get in even though there was room and no one was trying to connect.

-Favor points are not being saved, but favor items are. I currently have -800 or so favor points, and the only item I've got is Blood of the Fallen. Every few games it will accumulate, and then it will drop back down to -800.

-Occasionally, in the middle of a game, it will lock up for a second or two and then everyone gets auto-dropped, followed by "a p-p-p-p-p-p-player has left the game".

-Sometimes, for no apparent reason, the game will stop trying to connect you to one person--it appears that the game doesn't even acknowledge that person's presence even though his name appears--so you can never get into the lobby and must abandon the effort.

-It takes FOREVER to get into a lobby even when all goes well, giving one the impression that there are connectivity problems. This game uses SupCom's engine, which uses a similar P2P system. In SupCom, everyone was connected to each other within seconds if you had ports forwarded properly. At worst, you'd have to rejoin if something went wrong, and that wasn't too painful. In this game it feels like you should win an achievement for just being able to get in the freaking lobby. If this minutes-long connection dance is a feature of whatever fancy NAT system or netcode gymnastics you guys tried to do, this game won't last very long.

-Most Pantheons have a list of players you are connecting to, but half of them are just names with blank boxes that don't tell you their connection status, and they have 0 ping in the game. Are these AIs that have taken the place of players that have failed to connect? It doesn't feel like I'm playing humans sometimes, because when people leave the game, their name remains, but they are an AI. The game NEVER says who is an AI and who is still human, and it sucks the fun out when you don't even know if you're owning some nublet or just some AI. It's even worse if you suspect half your own team is AI when you are losing, because you feel like the game cheated you.

About 75% of games seem to fail before they even start, and 25% of the ones that start inexplicably fail in the middle, some for no apparent reason at all. This game's connectivity problems are far from over.

The router I'm using has my computer in the DMZ, and it's fairly new, so ports are not the problem.

Right well here are the issues I am having:

1/ Automatching - when it os forming a game, you can see a list of who is connecting to who.  Except as mentioned above, some players have absolutely NOTHING in their boxes - i.e. they will never connect.  And then the game starts with them as AI.  Why?  All evening I have seen the same player names in every game I have played who never seem to connect to anyone and end up as AIs in game.  Half of each game are AI players.

2/  What is worse is that there is no way to know who is AI and who isnt as the game doesnt indicate so - you just have to assume everyone with 0 ping is an AI as their player name remains.

3/ The game is very low tolerance for lag spikes.  If you get a single spike, you are automatically disconnected.  If you missed the message that suddenly told you you were disconnected from everyone else and don't check pings, you may carry on playing not even realising you are now playing a SP game!

4/  In the lobby if you quit a game because you know a number of AI players are going to join (because of point 1), the connection window in the corner remains all the way to the main game menu.  In fact it bugs the game forcing a full restart.  There are a number of bugs like this relating with connections that require game restarts (just try it!).

Basically you need to:

A/ Make it clear who is AI and who is a player

B/ Do not allow games to start with AI players like this - some games seem to not have players connecting to anyone. Why are they not removed from that game lobby and replaced by someone that can?

C/ Remove the ultra low tolerance for lag - if someone lags for a moment in counterstrike, they sure are not kicked! I have a DSL connection, but the occasional 1 second spike and Im gone?

D/ Run through the MP process and just see the buggy nature of it - how were they missed in the process?

The game is fantastic, it really is but these issues are strange because they surely should have been noted in testing?  I have faith you will resolve them quickly though.

Thats sucks dude, as i said above though in my post. Yesterday i had about the 70% problems online when in games (same as you did), but today its been 100% for me 4/4 ive been able to play,etc..

Hope it improves for you bud!
