Re: Battlefield 4 3659 port problem!

I would just like to chime in.
I have full access to my router and firewall settings etc - all those ports are open and I had this problem.

Nothing to do with the user, rather the server and/or EA.

Check your network connection and make sure that port 3659 (UDP) is open.

All my ports are open as per your response. Also, my firewall is totally open for BF4.

This problem still persists. Can you please look into it and stop fobbing it off as a port problem.... it's not a port problem as you can see from the forums. Lots of us have tested the ports and they are open as specified.

This is ruining the game for me. I've put up with other bugs, but this was introduced in the last patch as I hadn't had this problem before... but now it's making the game unplayable.

rubbish answer. the firewall is off and besides we had no problems until recently and then everyone has been reporting tese problems... server side **bleep** up.. FIX IT!!!

@XXXO77O4906 this literally just fixed my issue! :heart:

That hero2hero help.

Same here with Hardline. It sucks!

Hey there.

We struggled with this error for multiple weeks, trying everything up and down the road to fix this. Here is a list of what we tried unsuccessfully:

- Repairing BF4
- Flushing DNS cache
- Clean boot
- Replacing aged router with three different new routers
- Calling ISP for port blocking/port limiting
- Calling router manufacturer for device limitations
- Using a VPN
- UPnP off (router/clients)
- Network Device Detection Search Indexer off
- Client firewall rule (inbound 3659), firewall off
- AV off
- Smart Port Forwarding for port 3659 on every client
- Adding '+clientport 20xxx' to the command line arguments
- Router port forwarding for port 3659
- Router port forwarding for ports defined by '+clientport'

But we did not give up, and we finally found the solution, in a German forum, in a post from the beginning of 2013. Whenever you get the error about port 3659, it might be port 3659. But it might also be that 3659 wors flawlessly, yet another port, 443, does not.

So, here is what you do.

Leave all that stuff on - UPnP, Device Indexer, Firewall, AV, etc. No need for Smart Port Forwarding either, and no command line argument.

Get onto your router. Add static routes for every client you have that should play on the same server or play in general.

Forward port 3659 UDP AND 443 TCP to your IP.

Example:
Forward port 443 (TCP) to 192.168.1.2 port 443 (TCP)
Forward port 3659 (UDP) to 192.168.1.2 port 3659 (UDP)

This allows the first client to play, if the firewall allows the game through and nothing else is broken. Now, for every other client in your LAN, do the following:

Forward different ports to the next IP, also 3659 and 443.

Example:
Forward port 453 (TCP) to 192.168.1.3 port 443 (TCP)
Forward port 3759 (UDP) to 192.168.1.3 port 3659 (UDP)

The third client would be:
Forward port 463 (TCP) to 192.168.1.3 port 443 (TCP)
Forward port 3859 (UDP) to 192.168.1.3 port 3659 (UDP)

You get the picture. You can do this for however many clients your LAN has. Since we did this, we can play three people, one server, no rubberbanding, no disconnects, no issues.

Hope this helps everyone who suffered as much as we did.

PS: Don't give me XP, but share this post with those who you suffer in other places. I don't care about upvotes or anything like that. We all suffered through this, with EA support sadly unable to point out this simple solution and the repetition of support replies and then asking for flowers for regurgitated canned responses isn't waht any of us needed.

Why is it that we have to change our systems to stop a fault in their programming. They get the big bucks they should bloody well fix it seeing as it is their game that is broken not my computer.   

this did not work for me ive been trying to play for weeks but i keep getting the same red pop up ive tried different servers but with no luck " Check your network connection and make sure that port 3659 (UDP) is open."

Until today I played without problems since game release and today this 3659 port !@#@!$ came up. If think thats last BF for me

I forwarded all ports of BF4 and still get same error.

I have the same problems bf4 please fix this

Can u pls send me the screen shot how did u oppened ports. I think i did it correctly but i am not sure. So if u or anyone can show me how to do it i would appreciate it 😉 

EA didnt want to help me so i am asking some of u. Than you 😉

So, in order to play a game that we paid some people to make it for us(playable), it's our fault that it doesn't work cause we don't have SSD's? To play this 10 euro piece of garbage I need to invest another 150 for a SSD? This is OUTRAGEOUS! 

BTW it's 2017 and this still hasn't been solved. I know for sure that it's a patch related bug, that affects BF3 as well(before the game launched flawlessly), and it would cost the supreme gods at EA more money to fix it than they would have gotten from that point where it messed up the connection until now, from the game. It's a big large f you towards the people who bought the game.

2018 AND THIS PROBLEM STILL EXISTS WITH BATTLEFIELD 5 DUE FOR RELEASE IN A FEW MONTHS...SERIOUSLY FIX THIS * ... YES caps!

Eu reparei o jogo e funcionou aqui.

For now it's 2020. Still there. Recently installed game and getting this ***tty "3659"
