However, some players are encountering the "Failed to Join Session" error, preventing them from accessing online play. As the game was just released today, minor bugs are expected and will likely be addressed in future patches.Currently, there are no official fixes for the "Failed to Join Session" error in Elden Ring Nightreign. Nevertheless, some unofficial methods might help bypass this issue and allow you to play the game.Note: These fixes are not official and may not work for everyone, but they are worth attempting.

Fix Elden Ring Nightreign Failed To Join Session Error

The "Failed to Join Session" error in Elden Ring Nightreign primarily stems from connectivity issues, which could originate from your end or the game servers. Here are some potential solutions that might resolve the error for you:

Check your internet connection.

Create an exception in your firewall.

Check your NAT type.

Verify the game’s version.

Flush your DNS cache.

Below is a detailed explanation of each method:

1. Check Your Internet Connection

A poor or unstable internet connection is a common culprit for the "Failed to Join Session" error.

• Verify Connection Status: Run internet diagnostic tools like speed tests to assess your connection's stability.
• Identify Issues: Look for fluctuating speeds, packet loss, or high latency. These indicators suggest your internet connection might be the problem.
• Contact ISP: Unfortunately, you cannot directly resolve fundamental internet stability issues. The best course of action is to contact your Internet Service Provider (ISP) and report the problem to them.

2. Create an Exception in Firewall To Allow Elden Ring Nightreign

Sometimes, your firewall (Windows Defender Firewall or third-party antivirus software) might inadvertently block Elden Ring Nightreign, leading to the "Failed to Join Session" error.

• Allow Game Access: You need to create an exception for the game to grant it unrestricted access through the firewall.
• Antivirus Software: If you have an antivirus installed, it typically manages your system's firewall. In this scenario, you must create the exception within your antivirus software's firewall settings to ensure Elden Ring Nightreign has free access.

3. Check Your NAT Type

Network Address Translation (NAT) type can significantly impact in-game connectivity. There are three main NAT types:

• Open: Allows direct connections with any other NAT type.
• Moderate: Can connect with Open or Moderate NAT types but may have limited connections.
• Strict: Can only connect with Open NAT types and may experience frequent connection issues.
• Impact on Game: If your NAT type is set to Moderate or Strict, it might prevent Elden Ring Nightreign from joining online sessions.
• Solution: You should aim to change your NAT type to Open. The specific procedure for checking and modifying your NAT type variesdepending on your router model. Consult your router's manual or onlineresources for precise instructions before making this change.

4. Verify The Game’s Version

If there's a version mismatch between your game client and the server, orbetween your game and your friends' games, it will invariably result inthe "Failed to Join Session" error.

• Solution: Verifying the integrity of game files is the most effective way toensure you have the latest game version. If a newer version isavailable, this process will automatically download and acquire thenecessary files.
• Steps (Steam):
• Open Steam and go to your Library.
• Find Elden Ring Nightreign, right-click on it, and select Properties.
• Select Installed Files from the left sidebar.
• Click on Verify Integrity of Game Files...
• Note: This process can take some time and might involve the uninstallation and reinstallation of supporting software.

5. Flush Your DNS Cache

Although less common, a corrupted DNS cache can sometimes lead to connectivity issues like the "Failed to Join Session" error.

• Solution: Flushing your DNS cache can often resolve this.
• Steps (Windows):
• Press Win + R keys to open the Run dialogue box.
• Type cmd and hit Enter to open the Command Prompt.
• In the command prompt window, type: ipconfig /flushdns
• Hit Enter again.
• Close the window once the process is complete.
• Restart PC: Afterflushing the DNS cache, restart your PC to ensure the changes takeeffect. Then, rerun the game. This should hopefully resolve the "Failedto Join Session" error and allow you to play Elden Ring Nightreign.

Can You Play Nightreign Without Multiplayer?
