"Bad Version, server rejected connection"

[tviktor]

This happens when your DayZ client and the server you are trying to connect to have a build version mismatch.

There are two different "branches", or "builds", to choose between.
Stable is the main one and the one recommended when playing.
Experimental is where future updates and mechanics are tested in a smaller, more controlled, environment (fewer servers).
You need to match your build with the type of server you are trying to join.

For example; you might be running the latest Experimental build while the server you are trying to connect to is running the previous Stable build. Attempting to join will give you the error message Bad Version, server rejected connection.

In most cases it is likely you are running the Experimental build and are trying to connect to a Stable build server, as there are few experimental servers running.

How to solve:

Before doing this make sure your DayZ client is shut down and you are running Steam with admin rights. (Right click Steam > Run as Administrator)

• Right click DayZ in your Steam Library
  
• Click Properties
  
• Click the Betas tab
  
• In the drop down menu choose:
  NONE - opt out of all beta programs
  (no code is needed)
  
• Close properties.
  
• Start the game.

Ok so ive got the same problem, i choose the server, i press play....nothing happens, then i have - no message received for 1.2.3.4 while im in the menu....I was trying to make a character, but is doesnt save, and when login next time ------ im doing that from the scratch and still can not login...problem is the same.......now what i have noticed is - I installed the game just today, i had it installed some time ago but deleted it....now for some reason i dont have any dayz folders in My Documents section..even after i reinstalled it. I dont know how to get it back, so i dont have dayz.cfg and userdayzprofile...also i dont think i have anything in appdata folder. I tried the verify thing through steam - nothing -> all files are in place.
I guess my problem is that i dont have any dayz related stuff in My Documents but im not sure how to get them

followed the suggested instructions but am still unable to connect "Bad Version, server rejected connection"
also have uninstalled reinstalled , deleted dayz folder in %appdata% and documents.

If you're trying to connect to a community server then the problem could be server sided and you'll have to wait until the server owner updates his version.

Played fine last night, Now I get the bad server error. It seems like the servers launching are the "old version|" (unstable/experimental) The version I am showing as having is 1.0.1505 ??

I am getting a bad version server rejected connection error too but the server ( not mine ) and client ( me ) have the same version ( 151507 ). The server is modded, might that have anything to do with it?

i get the same message as stated above by a number of players i get the message no matter what day of the week is . so saying to some one who is asking for help and are you are saying they are arrogant because they do maintenance on Wednesday .you have not read properly what ppl are saying about the issue . any way im having same issues un ans re install mon to sunday tried betas try admin rights makes no difference . i noticed most servers are saying pop empty

[VESP]

As mentioned a few days ago i had problems joining despite having the same version as the server ( tried exp and stress test just to be sure and it always showed up that the server has 1.03.151507 ). A day later i could connect which looks like a mod was responsible because a few days later a mod the server was using ( Weapon Redux ) was updated while the server wasn't yet since it was midnight and the update arrived seconds ago. So we couldn't join again. I could rejoin the next day.
So from the looks of it it seems to be a client to server mod mismatch, at least in this particular case.
I hope this helps explain why we get that issue.

Servers need to update because they don't launch the application as often as players do. So at minimum every 3 hours usually 4 hours depending on what the host has set restarts to and if the provider updates servers between restarts. That's the big downside of modded servers, have an outdated or broken mod? You are effed. Mods break the game more than one way

so this is never fixed? same thing about this 2019?

Easily fixed. BIS takes the good mods and puts them into the game then disables mods in order to not split the already tiny community.

Logging in as admin to resolve the 'bad version' worked, so thanks. Though I fail to see why I had to do this today, to get to a stable server, when I had no problem yesterday.
