Hmmmmm, oki then, i will start off by saying this can not be fixed by a client. You think you fix it but this problem is very random. When you sit and click on random servers you are bound to access one or two of them. To suddenly say you need to start forwarding ports is the same as saying ‘i have been driving a car with wheels for the last few months, but after i added a new radio i have to change my wheels or else my car will not start’. Same thing :P. I have hundreds of online games that works fine with no issues, only this game, i had the same problem with BF3 which was a Punk Buster issue. This time i could not get it sorted out. 127.0.0.0 IP is a loop-back IP, this IP is for us Network Engineers for testing, please leave this IP alone. Thanks Again the restart your PC and Router is a myth, like i said it is random, when you view all the multiplayer games, try to join a server that shows you the ping next to it. Chances is one of them should work, and you would be able to play for 30min and no more. You will be kicked after 30 min or less, and when the server change maps you will also be kicked. You think you found a fix, and i promise you you still have the same issues, its just guys posting i did (wtf ever!!!) and it works and they are gone, and now they sit at their PC’s crying because they are back to square one and feel to stupid to post again. If you only recently got the game, some of these fixes might work, but dont et your hopes up. Fact is most of the guys here was playing this game for a long time, and suddenly they have to tweak stuff to get a very expensive game to work again, lol, gimmi a break. Lets hope the DEVS can fix this, because believe me, it is their issue, not ours. Over and out. ---

Ok, let’s try doing something instead of screaming at dice (however, if you read this, help us please) So what I 've tried (and did not work) - Repair battlefield 4 via origin - turn of my firewall - added a new rule at the firewall for that port - turn of pc and router - closed every program that could use this port in the background - updated punkbuster (and installed it as administrator) - tried to join another server (which I knew worked in the past) None of these things worked 😛 The game worked perfect a month ago, and suddenly i got connecting errors all the time (can’t play 7 min) I’ve been playing bf3 and bf4 on the same network and both games have this issue now (not in the past!) . So… i don’t think it is exclusive to bf4.? I can’t pinpoint when the problem started… Details about my network: - 16 users in total, don’t know which games (if any) they play and some have installed their wifi on the cabled network in this building (one central router for internet access) - i cannot access the router because I don’t have the password Can it be an update of another program is messing with this? (like avast! (wouldn’t be the first time )) Is there a way to see which applications use this port? Can i redirect my traffic via another port? Can i do anything at all? 😛 Does everybody have this problem? Or is there a common factor with all the people who have this problem. ---

Hi guys, What worked for me was : 1.Run and type CMD in the Run box. A command prompt window should open on screen. 2.Type ipconfig /release in the command prompt. 3.Wait a few seconds for a reply that the IP address has been released. 4.Type ipconfig /renew in the command prompt. 5.Wait a few seconds for a reply that the IP address has been re-established .6.Type ipconfig /flushdns in the command prompt. 7.Close the command prompt and attempt to make a connection. ---

Since the latest BF4 update I am now getting this problem on every map and server I play. I am unable to finish almost any map unless the game is over fairly quickly. Tried the DNS flush and IP reset. Made absolutely no difference as expected. Tried PB reinstall. Also made no difference (and does not use the port affected btw). This is not a client machine issue at all. No other internet dependent game on my PC is having an issue. Nothing has changed on my machine AT ALL other than the BF4 executables. And clearly I am not the only one affected - all of our machines have suddenly developed the same software or hardware fault? All at the same time? Really? Of course not. There is almost certainly one thing we all have in common though. A recently patched BF4 game that has been beset with development problems since it’s launch. It seems to me many of the patches that have been put out there are more steps back than forward. The developers need to look long and hard at their test scripts, routines and perhaps machines. They are clearly not robust enough or the machines are not representative enough of those in the user community. I really hope this works soon. There is a great game in there somewhere. ---

Lol… Dice dide a genious move here. I can see how the monday meeting went: **Jim** : Soo… we’ve getting a LOT of complaint on the gameplay lately. Netcode, crashes, killcam freeze, rubberbanding… what do we do? **Peter** : We’ll I’ve been working hard on debugging for the last 48 hours and I seem to be making some progress. I’ve found weaknesses in the core protocl of the comms-module fo… **Fred** : PORT 3659 !!! (silence) **Jim** : Um…what? **Fred** : Port 3659! Just make an error message stating the problem is port 3659 on the user’s end! **Jim** : Ok… uhm.. is it? **Fred** : That’s not the point! Have you ever tried configuring routing and network protocols!? It’s even harder than coding Battlefield! It will buy us at _least_ two months when people bust their ass off fighting with the router configuration. Do you want two months of uninterrupted crunch time, Peter? **Peter** : Well yeah, but.. **Jim** : Fred, we can’t just plain lie to our customers.. **Fred** : All is fair in love and war. And Battlefield. **Jim** : _sigh_… well then, Peter: new priority 1: Change error message. Priority 2: Fix bugs. I want a new patch by wednesday. See you next week, meeting adjourned.
