Moreover, while many players have managed to find certain workarounds for the same, there’s no official patch from the developers available yet.

That being said, this blog post discusses the various ways you can fix this error and continue enjoying the game in no time.


How To Fix Gotham Knight Failed to Join Session Error

Gotham Knight features an excellent cooperative mode that allows the players to join your game at any point in time.

Although gamers have several mixed opinions regarding it, the feature surely adds a dynamic and unique style to the gameplay.

However, many times, you may not be able to establish a proper connection with the server lobbies while trying to hop in on a quick session with your friends. The game would throw in an error saying, “You have failed to join the session.”

Fortunately, we’ve discussed certain workarounds that will allow you to get rid of the issue in no time.

Most of the solutions discussed here are gathered from the official Gotham Knights subreddit as well as the community discussions on Steam.


Make sure that you follow each step carefully and in an orderly fashion. Here’s what you need to do:

1. Check Your Internet Connection

Foremost of all, you should consider verifying whether your internet connection is working or not. If you have an unstable internet connection, you may not be able to join in a lobby. A lot of times, gamers also experience a surge in the bandwidth from their modem or router.

Most likely, this would be the primary reason why you’re not able to join the lobby in Gotham Knights. This game requires you to have a strong and stable internet connection to be able to function properly with no interference.

Even if you manage to join the server with an unstable internet connection, you’ll encounter issues such as high latency that would lead to lagging in your gameplay. To tackle the issue with ease, you may consider using a wired ethernet connection instead of a wireless one.

This will allow you to bridge any gap between the bandwidth and your internet speed. In case you have kept the modem away from your PC or console, consider keeping it a little closer to see whether it solves the issue for you or not.


Additionally, you may also contact your ISP and ask them to implement a static IP address to your router. This will help you make the online components of your game operate more efficiently by allowing it to be an open NAT-type network.

2. Check Gotham Knight’s Server Status

If your internet connection is working properly but you’re still facing issues with joining the game session, you should consider checking the server status before anything else. While there’s no official resource that allows you to do so, you may use third-party resources for the same.

For instance, the official Twitter account of Gotham Knights provides you with all updates related to the patches and ongoing issues with the game. You’ll always be notified ahead of time about any issues with the multiplayer feature of the game.

In case you get notified of any ongoing issues with the game servers, it would be in your best interest to wait until the issue has been fixed before trying to join another game. Once the issue has been fixed, you’ll be able to easily join the server.

3. Verify The Integrity of Your Game Files

If you are playing Gotham Knights on PC and encountering this error, then one of the best methods you can use to resolve the issue is to verify the integrity of your game files. This allows you to fix all sorts of problems with your game that are related to the game directory.


However, keep in mind that this only occurs rarely when some of the crucial game files are missing which might cause the game to malfunction and prevent you from joining a multiplayer session. You can verify your game files easily if you’re using a launcher like Epic Games or Steam.

These launchers have a built-in function that allows you to verify your game files and make repairs in case there are certain components missing from your game. It’s quite easy to do this – follow the steps given below, and you’re good to go:

For Steam

  • Foremost of all, launch Steam on your PC by either searching for it or double-clicking on its shortcut.
  • After accessing the launcher, navigate to the game library section and find the Gotham Knights game from the list of available games.
  • Then, right-click on the game and choose the “Properties” option.
  • Once done, head to the Local Files tab and then click on the “Verify Integrity of Game Files” option.

Lastly, just wait for the process to complete, which should take around 10-15 minutes, based on your network connection.

Once the process is finished, you’ll be notified about any missing files that are required to be downloaded. Afterward, just relaunch the game to proceed.

4. Connect To A VPN Network

A VPN, or virtual private network, has been touted by many players to be a sure-shot solution to get rid of any server-related issues with your game.

It’s a great way to access the game content through a secured network, which also keeps your private data secure.

On the contrary, however, many gamers on Reddit have reported that using a VPN doesn’t have any effect on the game at all unless you are trying to play it in a region where it is banned.


In general, though, using a VPN certainly makes sense for multiplayer gaming.

5. Allow Access to The Game Through Windows Firewall

Another reason why you might be having issues while accessing the game lobby is that it might be restricted by your Windows Firewall.

That being said, if you grant permission to the game through the firewall, you’ll be able to mitigate the issue in no time.

Permitting the game through the firewall allows it to access both the public and private domains of the network, which will allow the game to connect with the multiplayer servers with ease. Follow the steps given below to do so:

  • Start by searching for Windows Firewall in the search bar of your OS.
  • Then, click on the “Allow an app or feature through Windows defender firewall” on the left-hand menu.
  • Once done, you’ll get a list of all the applications installed on your system, out of which you’ll have to select the ones that you want to allow through the firewall.
