Re: PC BF4 LOST CONNECTION TO SESSION..

I have the exact same issue everything I've tried and still cant even get into a game match

Me too i can't get in any server

Hello @pipecapo 

I am really sorry about those issues with the game. What platform are you on? Have you tried to perform those troubleshooting steps, I`ve suggested in my previous post? Restarting your console/PC and router, might be a good start to fix this as well. Keep us posted on your progress.

Cheers,

Hello @rataratitaraton

What is your platform? Did you try this Connection Troubleshooting https://help.ea.com/en-za/help/faq/connection-troubleshooting-basic/ ?  Also, if you have this issues with Trial version or Retail (the base game) version, please clarify this.

BUMP. what is happening?!

 I am on a wired connection but still.

I have the same problem. But only with one server, and it is the ONLY server that i like and play oin constantly.

So i tried joining from Battlelog , and this is the error that i got : Check your network connection and make sure that port 3659 (UDP) is open

I tried lots of things to fix it. I really want it to be some problem from origin or something else. I want to play on my favourite server :\

I'm considering purchasing 2 copies of BF4 so I decided to go with a trial version first and demo the game.

This was happening on 2x Windows 10 Desktop PC's very badly, with only 1 running, it wasn't as bad, I Enabled QoS on my router and it seemed to have solved a big part of it, however, it still occurs on the 2nd PC all the time.

As a result, I went to a CMD prompt and typed IPCONFIG /FLUSHDNS, I then proceeded to run CCleaner, and finally, in a Windows Search I Typed %temp% and deleted all information in the folder before restarting the PC.

The 2nd PC was then able to join the same server as the 1st PC and play for approx an hour, after some libations, the 2nd PC persisted again with the error but only on FULL or CLOSE TO FULL servers. Empty servers connected fine and I could run the map as long as I wanted to without the error occuring. 

I again followed the above steps with no resolution. As a result I did further investigating and found a guide related to this issue, I then followed THIS GUIDE exactly, and still, the problem persists.

Should I save my money? As EA simply seems either incapable or unwilling to solve these problems, and I do feel as though I should'nt spend money on a deffective product or more hours fixing / troubleshooting connection issues before i purchase a product that clearly has serious connection deficiencies.

I post this in the hope it helps those that own the product troubleshoot some of the issues facing them during the daunting task of connection troubleshooting.

Also as shots fired at EA in the hope they realilize the product being marketed to the end user should not require the user to be a Troubleshooting Guru in order to make use of the product being purchased in Good Faith.

I have completed essentially all your tasks EA!! ALL of them!! i have wasted my whole day troubleshooting. Give me a straight answer instead of just pointing me in another direction!! Even though the game is 2 years old, it is still alive, and you need to be dedicated and help us!!! Please reply with a decent answer that will fix my problem...

P.S When I am waiting for other people to join the game, I have connection, however when enough people join for the game actually starts, THAT'S when I lose connection, hope this helps. Please answer (I am on the trial)

Hello @erikbukova12 

I am really sorry for those connection issues in Battlefield 4. Have you tried any of the troubleshooting steps, what were discussed in this thread previously? Restarted your console/router? What region are you in? 

You keep posting these same steps on both Bf1 and other Battlefield forums and 90% of people dont know **** on how to apply those fixes (including myself). Get your solutions straight so that everyone understands them! Goes to show how little you care about gamers and the community!

Hello @tilengoti 

I can totally understand how frustrating this can be. And we are trying to do our best to help all our players in need. Connection troubleshooting can be difficult, since it depends on so many individual settings and hardware variations. Let us know exactly, what kind of issue you are experiencing, on what platform, using which type of connection, and if you have already tried any steps to fix this, and we will try to help you in the best possible way.

Cheers,

well sead man

Well if you have to know I and experiencing an error ''you have lost connection to the session''! Let me explain it to you. I'm playing this game on a PC Windows 10 with proper specs to run the game twice if necessary. I have been getting this same error for like 2 months now and it came out of nowhere. The thing I have also noticed is that while loading a map, after a few seconds my loading stops for like 2 seconds, than it continues to load and again freezes for approximately 5 seconds and continues and finally freezes for about 10 seconds and continues just a little bit before disconnecting. If this tiny description is in any shape or form doing any good to you. I am also connected to a network using LAN cable so the connection is stable enough. Opening new ports, like every useless advice so far, did not help at all! Neither did turning sync on and off in Origin. And just to clear things out, I am getting these same problems on both Battlefield 4 and Battlefield 1 but not on any other online Origin, so to say EA games. If I were you I'd focus on this problem ASAP otherwise you will be losing players I guarantee you that. Things like that are very frustrating, especially when you pay a decent amount of cash to buy it in the first place. Hope this clearing thingy helps!

Hey @tilengoti,

thanks for that description. You're saying that's happening in BF4 as well as BF1. I also recently got a PC that, as you said, could run the game twice. Still BF1 did "stutter" at times, when it froze for a second, sometimes for 3-5 on some maps. I eventually got rid of this issue by turning off DX12 in BF1 (not applicable to BF4) and, more likely a reason, switching off Windows Gaming mode.

On top, I also turned off nVidia Share, but I turned it on again at a later point and it didn't have any negative impact, so it points to one of the above things. Maybe that helps for BF4, too.

@EA_Joker mate this legit helped. DX12 was an issue! Thanks!

Hey @tilengoti,

that's great to hear - and don't worry, there isn't a big visual difference between DX11 and DX12 so far really, so you're not missing out on anything.

Now enjoy the game, get back on the Battlefield and have a great weekend!

Hi,

I have "LOST CONNECTION TO SESSION" problem too. With Trial version BF4. My brother has full version without connection problem. So i logged to my account on his PC and suddenly "LOST CONNECTION TO SESSION" problem. It seems, It Does not matter to PC. Is it caused by trial version or specific origin account? I have BF 1 without this problem. I'm disappointed because I wanted to buy the full version of BF4, but after this experience....
