How to Fix Code Vein’s Multiplayer Not Working

Namco’s Code Vein game is an action RPG with an online multiplayer mode. However, some players have posted on Steam’s forum about Code Vein’s multiplayer mode not working. Consequently, those players can’t join multiplayer sessions to play Code Vein online.

Why is Code Vein’s multiplayer not working?

The most widely reported Code Vein multiplayer issue has an error message that says, Failed to initiate multiplayer session. That error message appears for some players when they try to summon friends for multiplayer games.

We will go through a couple of reasons why the multiplayer feature is not working in Code Vein:

• Incompatible Steam region settings – If the Steam region is not set correctly, joining multiplayer sessions in Code Vein will not work.
• Game bugs – Having many blood code gifts equipped is a bug that has caused Code Vein’s multiplayer to stop working for players. That bug primarily affects the base version of the game.
• Steam-related issues – Such issues can arise because of conflicting programs, Steam service failures, and security features like firewalls. If Steam crushes when installing games, this guide will help you.

There are numerous potential resolutions for fixing Code Vein multiplayer issues, and we outline them below.

What can I do if Code Vein’s multiplayer is not working?

1. Change the Steam download region

1. Open the Steam client.
2. Click the Steam menu and select Settings.
3. Click the Downloads tab on the left, select the Region drop-down menu and select your correct region from the list.
4. Press the OK button, then launch Code Vein, and try joining your friend’s game again.

2. Repair the Steam service

1. First, make sure Steam is fully closed.
2. Next, right-click the Start button and select Run.
3. Now input this repair command in Run’s Open box: "C:\Program Files (x86)\Steam\bin\SteamService.exe" /repair
4. Click OK to initiate the repair command.

The command above includes the default Steam installation path. If you haven’t installed Steam in its default directory, you’ll need to enter the full folder path you’ve installed it at in the command.

Also, note that this command requires admin rights. Therefore, make sure you run that command in administrator accounts.

3. Select the No Restrictions matchmaking option

1. First, launch the Code Vein game.
2. Open the game’s Options menu.
3. Then select Multiplayer.
4. Select to open Network Settings from the Multiplayer options box.
5. Turn off regional matchmaking restrictions by selecting No Restrictions for the Area Restriction option.

4. Disable Windows Defender Firewall

1. Click the Start button, type firewall in the search text box, and click the Windows Defender Firewall search result.
2. Then click Turn Windows Defender Firewall on or off to bring up Customize Settings.
3. Select the radio buttons for the Turn off Windows Defender Firewall options and press the OK button.
4. Try playing Code Vein online with the firewall off.

We recommend turning the firewall back on after playing Coin Vein. If this resolution resolves the game’s multiplayer issue, make sure Steam and Coin Vein are allowed through the firewall.

Also, if you’re using a third-party antivirus with a firewall, disable it from its protection settings menu.

If you can do so, select to temporarily disable its shields for a few hours before you start Coin Vein.

5. Clean boot Windows

1. Press the Windows key + R at the same time to launch Run, type the following command and press Enter to start System Configuration: msconfig
2. Click the Selective startup radio button, and uncheck the Load startup items checkbox to deselect that setting.
3. If they’re not currently selected, click the Use original boot configuration and Load system services to select those settings.
4. Click the Services tab, select the Hide all Microsoft services checkbox and click Disable all to deselect the non-Microsoft services.
5. Press the Apply and OK buttons.
6. Then select Restart to reboot Windows.

This resolution disables all third-party startup items and services that could be conflicting with the game. If Code Vein multiplayer works after clean-booting Windows, there was most likely a program or service interfering with the game or its Steam client software.

You can restore the original boot configuration for Windows by selecting the Load startup items and Disable all options. If you do so, however, you’ll need to identify what program or service is causing the issue.

6. Remove gifts and passives from your unused blood codes

1. Start Code Vein.
2. Look into your character options and uncheck any blood code you might have equipped.

Some players have been able to fix Code Vein’s multiplayer mode not working by removing all the gifts and passives for unequipped blood codes they’re not currently utilizing.

That may not be an ideal solution. However, that resolution is confirmed to fix a multiplayer bug for the game’s base version.

Contact Bandai Namco’s Code Vein support service for further troubleshooting guidance. You can submit a support ticket from Code Vein’s customer support page. Sign in to your Bandai Namco account there, and then click the Submit a Request button.

The potential resolutions above can feasibly fix a variety of multiplayer issues for playing Code Vein online. So, give those resolutions a try whenever Code Vein’s multiplayer doesn’t work as expected.
