How to Fix TEKKEN 8 Connection Timed Out

Bandai Namco has done a tremendous job by releasing the eighth edition of the Tekken series called ‘TEKKEN 8’ for the PC, PS5, and Xbox Series X|S platforms. Players can get into the legendary fighting game to win matches in the single-player and PvP modes. This 3D action fighting title is doing pretty well in the market but some bugs or errors are troubling a couple of players that we can’t deny. Well, the TEKKEN 8 Connection Timed Out error is one of them which seems frustrating.

As per multiple reports on the Steam community, the “Connection timed out. [Error code: A-00604-00898-l/J3V9-3E78USX2W6R]” occurs most of the time whenever players try to initiate a rematch. Though it requires players to reconnect to the servers, the connection timed out appears after loading for a while. Eventually, unfortunate players are getting prevented by the server connectivity issue in Tekken 8. We should also mention that the same error may also occur during a short 2-minute practice session or even before a fight.

It seems that Bandai Namco will need some time to optimize the server scalability and performance to reduce the connection timed-out error. The chances are high that somehow the huge overload to the servers by the number of active players is also causing the server connection errors. Whereas the network connectivity issue at your end can also trigger such errors at times. Now, if you’re also facing the same issue then check this article to get it fixed.

Launch the game to check for the issue.

10. Check for the Tekken 8 Server Status

Several players have reported that the Tekken 8 game servers are down or having maintenance processes at times which can also cause game joining issues. So, it’s suggested to check for the Tekken 8 server status from the third-party DownDetector Tekken status webpage to ensure whether any technical issue is there or not. In case, the servers are down then wait for at least a few hours and try again later. If there is no issue with the servers, you can head over to the next workaround.

11. Flush Your DNS Cache

You should also try clearing the DNS cache data on your PC by following the steps below. DNS cache data can get stored over a period which may cause multiple issues with the network connectivity. So, ensure to flush DNS manually to check for the connection issue again.

Open the Start menu > Search for cmd.
Right-click on Command Prompt > Click on Run as administrator.
Click on Yes (if prompted) > Copy-paste the following command and hit Enter:

ipconfig /flushdns

You’ll receive the ‘Successfully flushed the DNS Resolver Cache.’ message.
Next, execute the following command to register DNS:

ipconfig /registerdns

Then execute the following command to release the ipconfig:

ipconfig /release

Now, execute the following command to renew the ipconfig:

ipconfig /renew

Then reset Winsock by performing the command below:

netsh winsock reset

Close the command prompt and restart the PC to apply changes.

12. Change the DNS Address

Another thing you can do is change the private DNS address to the public Google DNS address manually on your PC to experience better server connectivity across all streaming platforms and multiplayer titles. You can try following the steps below to check for the issue again.

Press the Win+R keys to open the Run dialogue box.
Now, search and open the Control Panel.
Click on Network and Internet.
Select Network and Sharing Center.
Go to your Connections to select Ethernet or Wi-Fi.
Select Properties > Untick the Internet Protocol Version 6 (TCP/IPv6) option.
Double-click on Internet Protocol Version 4 (TCP/IPv4).
Click on Use the following DNS server addresses.
Use 8.8.8.8 as a Preferred DNS server address.

Enter 8.8.4.4 as the Alternate DNS server.
Click OK to confirm the changes.
Once done, reboot the PC to change effects immediately.
Finally, run the Tekken 8 game again to check for the issue.

13. Perform a Clean Boot

If none of the workarounds help, make sure to perform a clean boot method on your Windows system to avoid potential conflicts with third-party startup apps. The startup apps automatically start running in the background when you boot the Windows system. These programs unnecessarily consume system resources and data bandwidth which can affect the gaming experience. You can check the steps below to prevent unnecessary third-party startup apps.

Press the Win+R keys to open the Run dialogue box.
Type msconfig and hit Enter to open System Configuration.
Go to the Services tab > Enable the Hide all Microsoft services checkbox.

Click on Disable all > Click on Apply and hit OK to save changes.
Go to the Startup tab > Click on Open Task Manager.
Click on the Startup tab in Task Manager.
Now, click on the particular task that you want to disable. (OneDrive, Adobe Cloud, etc)
Select the task and click on Disable to turn it off.
Make sure to disable startup tasks that have a higher impact.
Do the same steps for each program that has a higher startup impact.
Once done, restart your computer to apply changes.
