Marvel Rivals Error Code 10 DNS troubleshooting on Windows

Quick answer: For Marvel Rivals Error Code 10 on PC, first check whether the game service is down. If services are available, restart the launcher and router, flush Windows DNS, and test a reversible switch to Cloudflare DNS. Change DNS back to Automatic if it does not help.

The video demonstrates changing IPv4 DNS to 1.1.1.1 and 1.0.0.1, flushing DNS, and restarting. This is an unofficial workaround: it can help when name resolution is the problem, but it cannot repair a server outage, account restriction, or corrupted game file.

What you need

  • An administrator account on Windows.
  • Your current network configuration, especially any custom DNS values, written down.
  • Marvel Rivals and its launcher fully updated.

Fix Marvel Rivals Error Code 10

  1. Check service status. Review the official Marvel Rivals site and launcher notices. If there is maintenance or an outage, wait instead of changing the PC.
  2. Restart the game and launcher. Exit Marvel Rivals, close Steam or Epic from the system tray, reopen it, and try again.
  3. Power cycle the network. Shut down the PC. Unplug the router for about 60 seconds, reconnect it, wait for internet service to return, and start the PC.
  4. Flush Windows DNS. Open Command Prompt as administrator, run ipconfig /flushdns, and look for the successful flush message.
  5. Test Cloudflare DNS on Windows 11. Open Settings > Network & internet, select Wi-Fi or Ethernet, choose DNS server assignment > Edit, select Manual, enable IPv4, and enter 1.1.1.1 as Preferred DNS and 1.0.0.1 as Alternate DNS. Save, then restart the PC.
  6. Verify game files. In Steam, open Marvel Rivals > Properties > Installed Files > Verify integrity. Use the equivalent verify option in the launcher you actually use.
  7. Test without VPN or proxy. Disconnect it temporarily, retry, then restore it after the test if required for your normal setup.

Why the DNS workaround can help

DNS translates service names into network addresses. A stale Windows cache or unreliable resolver can prevent the client from reaching login services even when general browsing works. Flushing the cache forces Windows to request fresh results. A different resolver changes only that lookup path; it does not increase frame rate or bypass an account or regional restriction.

How to undo the change

Return to DNS server assignment and choose Automatic (DHCP). If you previously used custom DNS values, restore those instead. Public Wi-Fi with a sign-in page may require Automatic DNS.

Warnings

  • Do not download DLL files or “network repair” tools from random sites.
  • Do not disable Windows Firewall permanently. If testing the firewall changes the result, add a narrow launcher/game rule and re-enable protection.
  • DNS cannot fix a Marvel Rivals outage. Repeated changes during an outage only make diagnosis harder.

FAQ

Is Error Code 10 always a DNS error?

No. It can appear during broader connectivity or service problems. DNS is one reversible test after status and restart checks.

Do I need to use 1.1.1.1?

No. You can return to your ISP’s automatic DNS. The Cloudflare values are used here because Cloudflare publishes the setup and reversal steps.

Will flushing DNS delete passwords or game data?

No. It clears cached name-resolution records, not accounts, saved games, or browser passwords.
