After 15 mins, i would drop out of game, very frustrating. so i decided to deep deep and google/research simular issues people have had. i came across and old artical about faults with BF3. it had simular faults, and a slight improvement to this situation. thus follows;
turn off UPnP off your router and go to start run😕ervices.msc and stop services, SSDP discovery and UPnP, also run msconfig and untick in start up same services. i found that the client closed down connection happens less. works for me.
Worth a try?
Still happens several times, every day
Ok, guys.
This is how I solved my problem:
All previous tests I did (as you can see all thread-long), I was behind multiple Network Equipment (Router, Load Balance, Modems and Modem/Router).
That means I was on Multiple NAT environment, and you'll see why that is important later.
I'm going to repeat: all the other games that I have/played, INCLUDING Battlefield 3, work / worked fine.
I've never needed to configure UPnP, DMZ, or Port Forwarding for them to work.
As I stated before in this topic, I have 2 Internet Connections with 2 different ISP.
One of them provided me a modem/router with locked configuration/firmware. I've tested BF4 directly connected to this ISP's router/modem, and that was it! No more "Client Closed Connection" problems.
So if you ask me what is the problem:
The BF4 makes a initial connection to EA servers to authenticate the client, before you can connect to the actual BF4 Multiplayer Server.
If you're on a Multiple NAT Network, this first connection FAILS...
...unless you're trying to connect to
1) an UNRANKED server or
2) a RANKED server with a number of players that is less than the "Minimum Players to Start" (e.g. less than 4 players, on default server configuration)
I understand that this problem might be affecting very few players that are in Multi-NAT, and that authentication to EA is important to keep cheaters outside of servers, but this is an issue that need to be addressed by EA / DICE, and not players. BF3 did not need this. Implement Multi-NAT support.
