What Causes The “Black Desert Error Code 12009?

Below, we will take a quick look at a few reasons why you are facing this error.

1. Third Party Firewall Or Antivirus

An overprotective third-party firewall or antivirus can be a reason for the error code. There is a possibility that there is a false positive interference with your system’s connection to the game server. This is because the security suite is flagging some of the files the game installer needs to run.

Administrative Privileges

In many cases, the game usually involves administrative privileges before particular tasks that are considered to be sensitive by Windows can be performed. If the game doesn’t have Administrative Privileges, it might malfunction, thereby triggering an error code.

2. DNS Inconsistency

This is common when there is a communication problem between the end-client and the game server. An inconsistent DNS (domain name server) could be the problem affecting the communication between the server and your pc. If you suspect this, you could level(flush) your current DNS value to fix the problem.

3. Old Version.dat file

This is a common cause prompting the error code 12009. The installer relies on old version.dat file when crosschecking the current version against the new one being installed. The installer can be forced to create a new file by renaming the old version.dat file. 

The game might be missing essential files for the connection process to occur. During startup, the requirement of all the data is not that important in the game.

However, when the game is loaded with a recognized connection, it requires all the files to be intact to load the maps. In other words, if there is an absence or when a particular file is missing, it might prompt the error code 12009.

4. VPN Or Proxy Connection Issues

Connection could be denied when you try to connect through VPN network or proxy server. Black Desert is notoriously known to encounter myriads of problem when it is forced to work through VPN or proxy. Black Desert Online Launcher is quite choosy when it comes to connection with a VPN network or proxy server. 

The Ip Ban 

This happens whenever there’s an IP Address associated with your internet connection that has been blacklisted by the game’s server. This could lead to an issue which sets off the error code. In most cases, the connection that was made available by the ISP is not a static one; which means the IP Address is frequently being changed.

As a result of this, one IP Address might get associated with multiple users. If this occurs, any terrible act being carried out by the other user might get you blacklisted through the game’s server. Don’t be mad; it’s the robots at work.

5. Ping Booster Interference
