Recently, many World of Warcraft users have been unable to login to their accounts. Whenever users tried to connect, they were greeted by “An error occurred. Please try again later. (51900309)”.
Changing FPS settings in the background
To change the FPS settings in the background at 30 frames per second, you must do the following:
- Open the Game Menu by pressing ESC or clicking on the Game Menu icon (red question mark on the bar) and clicking on System.
- Click on Advanced in the system menu.
- In the Advanced Options window, select the Max Background FPS check box and use the slider to set it to 30.
- Then click on OK.
Restarting the launcher
In most cases, the launcher can be disrupted, causing the error. Therefore, in this step, we will first completely close the launcher from the Task Manager, then restart it and start the game to solve the problem. For that:
- Right-click on the task bar and select Task Manager.
- You can also press Ctrl + Alt + Del and select Task Manager.
- Once the Task Manager is open, click on the Process tab and scroll down the list.
- Click on Blizzard in the list and select the Finish Task button.
- Repeat this process for all processes named “Blizzard” or “Battle.net” in the title.
- Now start the launcher by clicking on the “Battle.net” icon on your desktop and wait for it to charge.
- Click on the Games tab and select the World of Warcraft option.
- Click on the “Play” option and wait for the game to start.
Flushing Domain Name Server (DNS)
With this method, you must group the DNS yourself; it takes a few seconds and then you can log in to your account transparently.
This is only possible if there is a problem with your DNS. This way, you can quickly see how to rinse DNS with the command prompt.
Step 1: Open the command prompt (CMD) as an administrator by right-clicking on the Start button and then clicking on Command prompt (Admin). You can also press Windows + X. Or search also for “CMD”.
Step 2: Once the command prompt is open, type “ipconfig /flushdns” and press Enter.
Step 3: That’s all. Now close the prompt window and try again to connect. This time, you should be able to connect seamlessly without the 51900309 error.
Modify the configuration
A user discovered a workaround where editing the game configuration file allowed users to select and enter an area. Therefore, in this step, we will edit the configuration. For that:
- Navigate to the main game folder.
- Double-click on the “WTF” folder.
- Double-click on the “Config.wtf” file to open it and add the following line to edit it.
- Disable SETSelect AutoRealmSelect “1
- Start the game and check if the problem persists.
If this works for you, or if you have questions about other settings that I may have enabled, please leave a comment.
