5. Try Disabling the Mods
If you’re experiencing issues with server connectivity while playing a game, you may want to try disabling any in-game mods you have installed. Although mods can be helpful for customizing and enhancing your gaming experience, they can also be a source of trouble. By disabling them, you can check if they are the cause of the problem you’re facing.
6. Check the Internet Connection
It is important to check your internet connection thoroughly before coming to any conclusions, as a weak or unstable network can often cause issues. If you are using a wired (Ethernet) connection, consider switching to Wi-Fi or vice versa to ensure that the specific networking connectivity is not causing the problem. If your internet is working properly, you can then proceed to the next step.
7. Use Revert Turn in Tekken 8
Sometimes, the out-of-sync server connectivity problem might appear in your game during a turn. Well, you must revert the turn to the beginning of the round. Ensure the host player is heading to the game menu and clicking on Options. Then select Revert Turn. It’ll reset the game to the beginning of the turn and allow players to start over.
8. Try Disabling VPN or Proxy
It is likely that you are using a VPN service on your networking or gaming device. While a VPN can help you connect to game servers in different regions, it can sometimes cause problems with server connectivity.
