So I turned off my pc after playing. Then the other day I turned it on to play Dayz and when I was trying to join a server I got this message "Confirmation of Changes, Session Lost". I contacted the support for the game they sent me a guide to try to resolve this issue but it didn't help so now I am coming to you seeking for help. You are probably thinking you got VAC banned but I have already checked and I'm not banned http://www.vacbanned.com/ my id is http://steamcommunity.com/id/escamilla16/ check it for yourself. I aslo know for sure that I'm not banned because I joined in a friends PC and everything went just fine, but when he tried to join on his account using my pc, guess what the same message "Confirmation of Changes, Session Lost" I have already deleted Steam and re-download it and it didn't worked. I did everything on this guide that Dayz support sent to me When this message appears, it means that something on your network is blocking/disrupting the connection between you and the servers (which is why you would be able to connect from your friend's computer but not your own). Unfortunately, there could be numerous causes as to why your connection gets disrupted/blocked and this is something that we cannot fix on our end. The devs have written down a network troubleshooting guide below that could give you some hints as to how you might fix the problem: 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: http://windows.microsoft.com/en-us/windows/network-connection-problem-help#network-problems=windows-7&v1h=win81tab1&v2h=win7tab1&v3h=winvistatab1&v4h=winxptab1 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) http://portforward.com/english/routers/port_forwarding/routerindex.htm 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. Alternatively, you can try the following steps: 1. Start Steam and right click on DayZ in your game library (make sure that the game is not running). 2. Select the tab labeled "Local Files". 3. Click on the button labeled "Verify integrity of game cache...". 4. Start DayZ once the process is complete. If this does not solve the problem, here's a suggestion that is a bit more drastic. Please be aware though; you might have to reinstall your other Steam games afterwards: 1. Move the entire "C:\Program Files (x86)\Steam\SteamApps" folder to your desktop. Your "SteamApps" folder should now be at the following location: "C:\Users\<username>\Desktop\SteamApps". 2. Move the "DayZ" folder out of the "C:\Users\<username>\Desktop\SteamApps\common" folder and subsequently delete the "DayZ" folder. 3. Uninstall Steam while making sure the "SteamApps" folder is still on your desktop. 4. Install a new version of Steam. 5. Go to the new "C:\Program Files (x86)\Steam\SteamApps" folder. 6. Move everything inside the old "SteamApps" folder on your desktop to the new "C:\Program Files (x86)\Steam\SteamApps" folder. 7. Install DayZ again. I also tried doing a default settings restore to my modem, again didn't work. I'm out of ideas my last one is to do a full restore of my pc completely erase everything on it, start from 0. Would you try that? George
