Fix Marvel Rivals Login Errors 10, 220 & 5

It is incredibly frustrating when you just want to jump into a match and you keep getting hit with login error 10, 220, or 5. These errors usually happen when there is a communication breakdown between your machine and the game servers, or when a local security setting is being overprotective.

Why this happens

These codes indicate a handshake failure between your client and the Marvel Rivals servers. This is often caused by cached network data, corrupted installation files, or your Windows Firewall mistakenly flagging the game executable.

What you'll need

You will need administrative access on your PC and your game launcher (Steam or Epic) fully updated.

Steps

1. 01
   Perform a full power cycle by shutting down your PC or console and unplugging your router for 30 seconds, then restart everything to clear temporary network glitches.
2. 02
   Check official server status pages to ensure the game is not currently experiencing a global outage.
3. 03
   Verify your game files in Steam by right-clicking Marvel Rivals, selecting Properties, navigating to Installed Files, and clicking Verify integrity of game files; for Epic, use the three-dot menu, select Manage, and click Verify.
4. 04
   Flush your DNS cache by searching for cmd in the Start menu, right-clicking to run as administrator, and typing ipconfig /flushdns followed by Enter to clear stale network paths.
5. 05
   On PS5, navigate to Settings, select Users and Accounts, go to Other, and select Restore Licenses to refresh your digital entitlements.
6. 06
   Add a firewall exception by opening Windows Security, selecting Firewall & network protection, clicking Allow an app through firewall, and adding MarvelRivals.exe from your installation folder with both Private and Public boxes checked.

Still not working?

If you are still unable to log in, verify that no third-party VPN or antivirus software is actively blocking the game connection. Try disabling these temporarily to rule them out as the culprit. If the error persists specifically after a game update, you may need to wait for a hotfix from the developers if the issue is tied to your specific region or account flag.

Frequently asked questions

Will verifying game files delete my personal settings?

No, verifying your files only replaces missing or corrupted game data and will not touch your account progress or saved custom settings.

Does this error mean my account is banned?

Usually, no; error codes 10, 220, and 5 are almost always related to network connectivity or installation issues rather than account status.
