Instant Session Lost
Closed, ResolvedPublic


I am having an issue where I can not even join a server. When I attempt to join a server, it says "Waiting For Host" and then kicks back to the server selection screen stating "Session Lost". It appears the BattleEye is initializing properly, but I can not join any server. I have no reason to believe my VAC is banned and I have checked it; it appears to be fine. I have uninstalled and reinstalled the game several times, verified game cache via steam, and deleted the BEclient.dll to try and get the game to connect to no avail. I'm at a loss right now. I will mention that I used to live in the U.S. when I was playing previously, but have since moved to Australia where it does not seem to work any longer. I highly doubt this has anything to do with the issue, but stranger things have happened. If anyone has any information or tips on how I can get back into the game, it would be greatly appreciated.

Thanks for your time.

Hi woodenrims,

Please try upgrading to the experimental version and subsequently downgrade to the stable version and see if that helps:

  1. Open steam
  2. Go to games library
  3. Right click on DayZ
  4. Select "Properties"
  5. Select "BETAS" tab in the properties menu
  6. Then select the desired version from the drop down box
  7. Close the menu and the game should update/backdate to the requested version


I have done this and nothing changes. Any other ideas?

I checked your account just to be safe and unfortunately, this is something that we cannot fix on our end. Please refer to the network troubleshooting guide below:

  1. Check all the physical devices on your network to ensure they are plugged in and powered on.
  2. Perform a connection test on each device connected to the network. For reference, here is a list of platform-specific troubleshooting guides:

NAT Types:

  • Open
  • Moderate
  • Strict

Open NATs can connect to any of the three types. --> Probably the least common type
Moderate can only connect to open and moderate. --> Probably the most common type
Strict can ONLY connect to open.
Strict NATs are a difficult problem with peer-to-peer games. Since most people don't have open NATs, the player with a strict NAT won't be able to find many joinable games.

Also, if the player with a strict NAT does manage to join a game, if another player with a moderate NAT joins later, the player with the strict NAT gets kicked out.

Another problem is that sometimes the ISP (Internet Service Provider) is also behind a NAT, which often means even if you have a direct connection to the internet (without a router/firewall), the ISP still acts as a strict NAT.

Port Forwarding:
The following Ports need to be open on your router to connect to the online servers:
TCP 80, UDP 88, UDP 2302, UDP 2314, UDP 2326, 2338

If you need assistance with opening these ports, please refer to the following website for more information (you will need to know your router brand and model, as the website guides are based on specific routers)

Here are some additional tips that have helped many players improve their connectivity:

  1. Make sure your router's firmware is upgraded the latest version (very important).
  2. Unplug your router for 10 minutes and plug it back in. Some older routers degrade in performance over time until it is rebooted, similar to a PC.
  3. Disable any firewall or other network filtering for the game.
  4. Enable uPnP (universal plug and play) on your router.
  5. If you don't care about security, enable DMZ (de-militarized zone) on your router for your PC's address. This turns off all of your router's firewall features for that specific PC.
  6. Run 'cmd' in administrative mode and use command ipconfig /flushdns
  7. Contact your ISP and ask them what your DNS setting should be.

Direct Connection:
If you are still having issues connecting to the online servers after trying the above steps, try connecting your broadband modem directly to the console or PC you are playing the game on. This can help determine if the issue is related directly to the router or another source.
