Check your network connection port 3659 (UDP)

I’m having this issue since the patch of late february. I’ve never had any connection issue before. I keep getting the 3659 UDP error every now and then. I’ve opened all required ports in my modem as requested here http://answers.ea.com/t5/Battlefield-4/how-to-open-udp-port-3659/td-p/2378473 [answers.ea.com] I followed a detailed guide on www.portforward.com because EA redirected me to that site. I’m 100% sure my ports are opened now. I also created a new inbound rule in my Windows firewall advanced settings for port 3659. No matter what I do, I keep getting this error. Any help guys, please?

Same error after newest patch, before that never had this error. Updating punkbuster helped for yesterday but today the problem is back again. Seems to be related to certain servers.

same problem like you guys, never had this before, something is wrong after the last patch, ea/dice get it together already!!!

and yeah i know about smart port forwarding etc

All it’s left to try for me is just updating punkbuster. I’ve already done anything possible to open requested ports for BF4. I’ll give PB a try when I’m home.

guys, problem isnt in router with port, i took my pc to friends and tried on him network, still this problem. (he play normaly bf 4 without problem), and also i tried formated HDD (delete full hdd and reinstal win) dont work,

Aside from the killcam glitch I have been playing without any issues, until 10 minutes ago I got this error for the very first time. I do not think it is client side related to be honest.

i cant 1-2 month play bf, i cant log any server.. just this error

I don’t get this error but what I would try is getting a friend with a known working machine to come to your house and try their machine over your internet connection on BF4. If their machine works normally then it isn’t your internet connection / router / internal network setup. If their machine doesn’t work normally then the issue is your internet connection / router / internal network setup.

Try your machine round their house on their connection. If it works normally then the problem is not with your machine either. If it does work normally then your machine is the problem.

Things that are likely to block ports on your machine are anti virus or firewall software, programs that host a service like web pages or communication software. As a test try running BF4 on a known working internet connection with nothing but BF4 running.

Your ISP may also be using traffic management which gives too low priority to the traffic on the port causing the connect to randomly respond too slow. I had this with an ISP when playing BF2142 years ago. Swapped ISP and the problem went away instantly and never came back.

This is unlikely to be a DICE / EA problem or everyone would have it.

This is nonsense. I was able to play the game before the patch of the 25th of february. The patch brought this issue. The problem is not in my modem. Fact.
And if it was my modem, it would be fixed doing what EA says here http://answers.ea.com/t5/Battlefield-4/Port-3659-UDP/td-p/2460206. [answers.ea.com] I opened the ports and it doesn’t get fixed.

Whew… this thread… 11 pages??? Such an abundance of bad advice and horrible ideas… videos from obviously clueless people ( 10 min + and the tabs he has open in his browser should be immediate red flags ) lots of mod deleted posts.. not a single answer from EA ??

I feel bad for the peeps that KNOW what they are talking about.. plenty of good advice from those few posts… anyone trying to give advice that involves a fix should always be starting with a couple key items..

  1. REBOOT YOUR HARDWARE… this means your computer, your modem and your router if they are separate hardware devices.. and like someone mentioned.. UNPLUG YOUR NETWORKING HARDWARE for at least 15 seconds!!! if you don’t know why you need to do this, I am not going to bother explaining it..

  2. Assign your pc a static ip on your network within the subnet.. it helps especially when multiple pc’s are playing at the same time..

  3. Refer to step 1..

I was a network admin for years and quit to work in construction.. too many variables from top to bottom that can make something on a pc not function as desired…

that is why you will see things in this thread that actually work for some ppl but in reality are not a real solution .. just a possibility…

good luck peeps

Cheeze out

The only fact you have is as far as you can tell it worked before a certain date. Try the advice I posted above to prove where the fault is coming from.

Thanks for the advice guys.

Just strange that it was working fine before SA…what changed? Not my ISP or modem or anything…just the BF4 DICE (EA) software.

So why is it suddenly an issue…If we knew that I think we will find the real problem.

BTW, it is not just me as you can see by the 11 pages of posts and that is only the ones that found this thread.

I also updated the video driver too in desperation as noted by another adviser regarding this exact problem.

Still no good!

“Game disconnected: Client closed down connection. Check your network connection and make sure that port 3659 (UDP) is open” 2.28am

I was able to join a couple servers the past couple days, but they had to be nearly empty for me to do so. Has anyone else tried to join low population or empty servers and had success?

Whenever I attempt to join a server with 5 or more people in it, I will always get the error, even if I had just joined it previously while it was empty.

yesterday i still play BF4 but today i have this problem first time and how to fix it or dice/ea don’t care about us anymore?

I just got this message once but can play at most servers. I also dont have a router I can config (FTTH).

yesterday I was playing just fine, now this?
you DICE are really pathetic patching your stuff
