[BF4] Port 3659 Open But UDP Error Persists

Hi there,

Many of you have probably heard of this problem.

I can join a game but within seconds the Battlefield executable freezes and I am kicked out with the Error:

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

Please note, this is happening today. This has never happened before. I last played 3 days ago without a problem. I cannot think of any BF4 or Windows patches that may have caused this problem over this time period. Nobody else has fiddled with our router,- I'm the go-to person for any internet problems in the household.

----------------------------------------------------------------------

As you can see in the link below... Port UDP 3659 is open. I logged into our Thomson gateway router myself and configured the open port

----------------------------------------------------------------------

Solutions I have tried:

1. Opening multiple ports and restarting both router and my PC

2. Adding new port (inbound/outbound) rules to Windows Firewall

3. Completely disabling Window Firewall

4. Tried both Wifi and Ethernet connection

5. Contacting EA support - no success

----------------------------------------------------------------------

I work in IT and I'm clueless.

Help...

I had the same problem with bf4 and matchmaking failed on bf1. LAST FIX that worked for me: if you have shared your internet connection via your pc, you are not able to play any of those online. Go to Network->change adapter settings right click on the wifi/ethernet connection that you use then properties and disable sharing internet!

December 2019 ... is it still possible to have this defect and not have any solution?
I have already EVERYTHING that has been suggested, for many years, since I started playing with BF4 ... I do not list all the problems I had to be able to start a game with the newly purchased BF4 (also changes to the Winzoz registry for the latency of the drivers!?! which should NOT have been necessary ... but BF4 is BF4 :-() and after years of playing, without touching anything, now it makes me this defect at random!
And I already know that EA-DICE won't do anything, because they don't care about old games anymore (they have already pocketed what they could and now it's just an "unproductive expense") and they are having trouble on the last BF5 without combining anything good ... I see (I have that too, unfortunately).

I'm closing this thread to stop it being necroed.

If you have any issues with Battlefield 4 please make a new topic about the issues you are having and what kind of steps you have tried to solve it.
