Gotham Knights multiplayer not working – Failed to join session

Gotham Knights can be played with a friend in multiplayer co-op mode, but the feature is not without its drawbacks. When you try to join a friend, you might see a “Could not join session”error, which will make you wonder why multiplayer isn’t working in Gotham Knights. If you can’t invite friends, here’s what you need to know about this issue.

Gotham Knights failed to join session (multiplayer not working)

While the developers don’t have an official fix or workaround for the Failed to Join Session error, it’s most likely a startup time issue that will eventually be fixed. This was reported to the developers and the page mentioned “Investigation Underway”. If you encounter any other multiplayer bug that is not already mentioned in bug reports, you can report it here. It seems like players can’t invite friends, but they can play with random players, so if you really want to explore multiplayer, this is an option right now.

And if this problem appears in the future, there may be several reasons why it occurs. It could be your internet, game files, or problems with the game server.

Check your internet connection

If you are unable to join even random players during the matchmaking process, you most likely have internet connection problems. Reset your router and try connecting again. On a PC, make sure your antivirus software or firewall is not blocking your connection to the game server.

Check if Gotham Knights servers are down

Another reason Gotham Knights multiplayer might not work is because the servers are down. If so, there is nothing you can do until the servers are online. Keep checking threads online on Reddit, Discord, and other gaming forums to see if other players are experiencing similar issues or not.

If an error occurs, you can close the game and start over to see if a fresh launch fixes it. You can also check your Steam game files to fix any corrupted files.

Check Steam Game Files

• Launch Steam.
• Find the game in your library.
• Right-click the game and select Properties.
• Find the “Local Files”tab.
• Click “Verify Integrity of Game Files”.
• After the process is complete, restart the game.

These are all potential fixes for the Failed to Join session pickup error that appears and why multiplayer is not working. While you’re here, check out our Gotham Knights guides.
