Fix Lethal Company Multiplayer Not Working or Not Able to Join Friends

Luckily, there are a couple of workarounds mentioned below that should come in handy for you. We’ll recommend our readers follow all methods until the party joining error has been fixed. So, without further ado, let’s jump into it.

1. Force Close and Relaunch the Game

Before doing any other workarounds, try force closing and relaunching the game on your PC to ensure there is no temporary cache data issue present on the system. Forcefully closing the game can also prevent background running game tasks from interrupting other tasks.

  • Close the game and exit Steam.
  • Press the Ctrl+Shift+Esc keys to open Task Manager.
  • Click on Processes > Select Lethal Company or Steam task.
  • Click on End Task > Once done, relaunch the game.

2. Reboot the PC

It’s highly recommended to reboot the PC manually before following other troubleshooting methods until the problem has been fixed. Sometimes a normal system reboot can fix multiple issues with the glitches or program data caches. To do that:

  • Open the Start menu.
  • Click on the Power icon > Click on Restart.
  • Once the system reboots, check for the issue again.

3. Run Lethal Company as an Administrator

Make sure to run the game executable application as an administrator to avoid user account control regarding privilege issues. The chances are high that your game application is getting blocked by the system admin permissions. To do this:

  • Right-click on the LethalCompany.exe app on your PC.
  • Now, select Properties > Click on the Compatibility tab.

  • Enable the Run this program as an administrator checkbox.
  • Click on Apply and select OK to save changes.

4. Check the Internet Connection

It’s suggested to check your internet connection at your end to ensure there is no network issue or not. A slow or unstable internet connection can cause multiple issues whatsoever. If you’re using a wired (ethernet) connection, try using a wireless (Wi-Fi) connection or vice versa to check for the issue. You can also try using a different network to cross-check it. Additionally, you can try power cycling the Wi-Fi router to check if the networking glitches have been fixed or not.

5. Update Lethal Company

Sometimes an outdated game patch version can trouble you a lot with the multiplayer sessions or joining the party. It’s recommended to check for the game updates manually by following the steps below.

  • Open Steam > Go to Library.
  • Right-click on Lethal Company.
  • Select Properties > Click on Updates.
  • Go to Automatic Updates.
  • Select Only update this game when I launch it.
  • It’ll automatically install updates whenever available.

6. Scan and Repair the Game Files

Sometimes corrupted or missing game files on the PC might also trouble you while starting the game. It’s always better to verify and repair the game files by following the steps below on your PC to avoid errors.

  • Open the Steam client > Go to Library.
  • Right-click on Lethal Company.
  • Go to Manage > Select Properties.
  • Click on Local Files > Select Verify integrity of game files.

  • Wait for the process to complete.
  • Once done, reboot the system to apply changes.

7. Update the Network Driver

You should try updating the network adapter driver on the PC to ensure there is no conflict happening with the networking connectivity. Sometimes your internet connection might have a good signal or speed but the network adapter may trouble you due to driver-related issues. To fix it:

  • Search for Device Manager from the Start menu and open it.
  • Double-click on the Network adapters.
  • Right-click on the network device.

  • Click on Update driver > Choose Search automatically for drivers.
  • If an update is available, it’ll automatically be installed.
  • Once done, reboot your computer to change the effects.

8. Create a New Lobby with your Friends

The game servers can easily be filled up and the rest of the players will have to wait in the queue. In that case, the server overload may end up with party joining errors & more. So, you should retry joining the lobby multiple times and then create a new lobby with your friends that would come in handy.

9. Whitelist the Program on Windows Firewall

Another thing you might need to do is whitelist the Lethal Company program on the Windows Firewall protection to reduce potential issues. It usually allows the game program to run smoothly without any further issues. To do so:

  • Open the Start menu > Search and open Control Panel.
  • Click on Systems and Security > Go to Windows Firewall.
  • Choose Allow an app through Windows Firewall.

  • Then select Change Settings > Choose Allow another app.
  • Click on Browse > Choose Lethal Company.
  • Now, click on Add > Save changes to check for the issue again.

10. Add an Exclusion of the Game to Antivirus

It’s also recommended to add the Lethal Company program as an exception to the antivirus software. This method will help in fixing potential issues with the multiplayer sessions. To do so:

  • Press the Win+I keys to open Settings.
  • Click on Privacy & Security.
  • Now, click on Windows Security.
  • Select Virus & Threat Protection.
  • Click on Manage Ransomware Protection.
  • Turn ON the Controlled Folder Access toggle.
    • If prompted, click on Yes.
  • Click on Allow an app through controlled folder access.
    • If prompted, click on Yes.
  • Next, click on Add an allowed app.
  • Navigate to the installed game directory.
  • Browse and select the LethalCompany.exe app.
  • Click on Open to add it.
  • Reboot the PC to apply changes.

11. Turn Off the VPN Service

Using any kind of VPN (Virtual Private Network) might be useful enough in most cases but not every time. The chances are high that VPN service can also bring server connectivity issues to the games. Not only does it cause ping delay issues but also has higher latency. Therefore, we’ll need to disable VPN services manually.

12. Reinstall Lethal Company

  • Wait for the uninstallation process to complete.
  • Exit the Steam client > Open File Explorer.
