The Open Beta of Call of Duty: Black Ops 6 is here and will run until Sept. 4. This game is now available for anyone who preordered or prepurchased the game. Although this game offers fast, fluid, and wild action, some bugs and errors kill the gaming fun. One common problem many players face is the “Unable to join game session” error. According to reports, players receive an “Unable to join game session” error when they start the game. If you also encounter the same problem, this guide has covered all possible workarounds to fix it.
How to Fix Black Ops 6 Beta “Unable to Join Game Session” Error
Many players have already tried closing the app and trying again several times to fix the “Unable to join game session” error in BO6, but that doesn’t work. If the same thing is happening to you, try all the workarounds below one by one to resolve the problem.
Try Playing During Off-Peak Hours
Usually, the “Unable to join game session” error in BO6 occurs when many players attempt to connect to the game’s servers at a time, and that causes a server strain. So, wait and try joining it during off-peak hours.
More than anything, the likely cause of this error is not on your end but the number of players trying to play the game. The developers have increased the number of servers since the beta launch. So, the occurrence of this error must have been reduced, but during the weekend, it can still get pretty crowded.
Restart the Game or Device
Next, try restarting the game and your device, which can refresh the connection and help fix the error. Close the game completely, reboot your device, and then try playing the game.
Check the Current Server Status
You might receive this error if the main game’s server is down. Make sure to check the current server status. To do this, visit the official Activision website or social media channels for the latest updates. If the servers are down for any reason, wait until they return online.
Check Your Internet Connection
A poor or unstable internet connection can also be one of the root causes of this error, so make sure your internet connection has no issues. You can try resetting your router or modem or switching the connection from WiFi to Wired for a more stable and reliable connection.
Repair Game Files
Sometimes, missing or corrupted game files can also trigger this error, so the following workaround includes repairing such game files. Here is how to do it for Battle.net and Steam.
– On Steam:Go to the Steam library >> Right-click on the game >> Properties >> Local Files >> Verify integrity of game files.
– On Battle.net: Go to the CoD tab on Battle.net >> Select the cog wheel next to the “Play” button >> Scan and Repair >> Begin Scan >> Yes.
Disable Third-Party Applications and Overlays
At times, third-party apps and overlays installed on your system can interfere with the game’s functionality and cause this error. Try turning off any unnecessary third-party apps and overlays and then relaunching the game. You can do this from the Task Manager. Check which apps use excessive memory or RAM and close them.
Clearing Cache and Temporary Files
In the following workaround, try clearing your device’s cache and temporary files, which can help resolve several issues and errors, including the “Unable to join game session” error. On consoles, you can do this through the system settings, and on your PC, you can do it by clearing your browser cache.
Disable Your Firewall or Antivirus Program or Set an Exception
Your firewall or antivirus program can sometimes block the game’s server connection. Therefore, try temporarily disabling your security program. If that works, try adding the game to the exception list on your firewall or antivirus app.
That’s all for this guide on how to fix the Black Ops 6 Beta “Unable to join game session” error.
