Fix Marvel Rivals Error Code 10 - Connection Issues

If you are staring at Error Code 10 while trying to launch Marvel Rivals, it means the game client is failing to establish a stable handshake with the servers. This is usually caused by a local network hang, corrupted game files, or your security software being a little too aggressive.

Why this happens

Error Code 10 indicates a communication breakdown between your local machine and the game servers. It typically stems from outdated network cache, blocked firewall ports, or incomplete installation files.

Steps

1. 01
   First, visit Downdetector and search for Marvel Rivals to ensure the servers are not experiencing a global outage. If the servers are down, you simply have to wait for the developers to restore service.
2. 02
   Unplug your router from the power outlet for at least 30 seconds to clear your network cache, then plug it back in and wait for the connection to stabilize before relaunching the game.
3. 03
   If you are on Steam, right-click Marvel Rivals in your library, select Properties, go to the Installed Files tab, and click Verify integrity of game files. This forces Steam to replace any missing or corrupted data blocks.
4. 04
   Open Windows Security, navigate to Firewall and network protection, and select Allow an app through firewall. Find the Marvel Rivals executable, click Change settings, and ensure both Private and Public checkboxes are selected.
5. 05
   Change your DNS settings to Google servers to bypass ISP routing issues. On PC, set your IPv4 DNS to 8.8.8.8 for the Preferred and 8.8.4.4 for the Alternate, then save your network adapter settings.

Still not working?

If you have tried all the steps above and are still seeing Error Code 10, your ISP might be routing traffic poorly, or a local security program like a third-party antivirus is interfering. Try temporarily disabling any active VPNs or secondary antivirus software to see if the error clears. If you continue to see the error across different network types, your account profile may have a temporary server-side lockout.

Frequently asked questions

Will verifying game files delete my progress?

No, verifying your game files only checks the integrity of the installed software. Your save data and account progress are stored on the game servers, not your local drive.

Is it safe to change my DNS settings to 8.8.8.8?

Yes, switching to Google DNS is a standard troubleshooting step that is safe for your computer and will not impact your internet security.
