Understanding the Error

Dev Error 5820 typically indicates a communication problem between your game and the Call of Duty servers. This could be due to problems on Activision’s end, issues with your internet connection, or conflicts with your game installation.

Troubleshooting Steps

  1. Check Server Status:

    • Visit the official Activision website or social media channels (like Twitter) to see if there’s a known server outage or maintenance affecting Black Ops 6. If the servers are down, you’ll need to wait for Activision to resolve the issue.
  2. Restart Your Game and System:

    • Close Black Ops 6 completely and restart your console or PC. This simple step can often resolve temporary glitches.
  3. Restart Your Router/Modem:

    • Unplug your router and modem, wait 30 seconds, and then plug them back in. This can refresh your internet connection and resolve network-related issues.
  4. Verify Game Files (PC):

    • If you’re on PC (Steam), verify the integrity of your game files through the Steam client. This checks for any corrupted or missing files that could be causing the error.
  5. Run as Administrator (PC):

    • Try running the Black Ops 6 executable file as an administrator on your PC. This can sometimes resolve permission issues that interfere with the game’s connection.
  6. Check Your Internet Connection:

    • Ensure you have a stable internet connection with sufficient bandwidth. Test your connection speed and consider using a wired connection (Ethernet) for better stability.
  7. Update Network Drivers (PC):

    • Make sure your network drivers are up to date. Outdated drivers can sometimes cause connectivity problems.
  8. Disable Firewall/Antivirus (Temporarily):

    • Temporarily disable your firewall or antivirus software to see if it’s interfering with the game’s connection. If this resolves the issue, add Black Ops 6 as an exception in your security software.
  9. Clear DNS Cache:

    • Open your command prompt (as administrator) and type ipconfig /flushdns then press Enter. This can resolve DNS-related connectivity issues.
  10. Contact Activision Support:

    • If you’ve tried all the above steps and are still experiencing the error, reach out to Activision Support for further assistance. They may have specific troubleshooting steps or be aware of known issues affecting certain players.
