What does marvel rivals error code 4 mean and how can I fix it?

[sophiadasy]

Marvel Rivals fails to launch (or disconnects) with error code 4 on my device. I’ve reinstalled the game, updated drivers, and checked my connection but no luck. Need targeted fixes (cache, file verification, account/server checks) depending on platform (PC/console/mobile).

Error code 4 in Marvel Rivals usually points to a connection or account issue. Try these quick fixes:

• Check server status: Sometimes the game servers are down.
• Clear cache: On mobile, clear app cache; on PC/console, restart the launcher/device.
• Verify files: On PC, use the game launcher’s “verify integrity” option.
• Re-login: Log out and back in to refresh your account session.
• Stable connection: Use a wired connection or reliable Wi-Fi.

If none work, contact Marvel Rivals support with your platform details—they can check your account specifically.

Error Code 4 usually means the game failed to launch or lost authentication/connection often caused by corrupted local files/cache, a blocked connection, or an authorization issue. Try the platform-specific steps below, then contact support with logs if it keeps happening.

PC
• Verify/repair game files in your launcher (Steam/Epic/etc.).
• Fully clear the game cache/temp (look in the game folder, %appdata% or %localappdata% for MarvelRivals folders) and then restart.
• Run the launcher/game as Administrator, disable overlays (Discord, GeForce Experience), and turn off VPN/proxy.
• Add the game to firewall/antivirus exceptions and update GPU drivers + DirectX/VC++ redistributables.
• If persistent: uninstall, delete leftover game folders, reinstall.

Console (PS / Xbox / Switch)
• Full power cycle (shutdown, unplug for 30s, then restart).
• Clear console cache / remove and re-download the game.
• Sign out and back in, check NAT type / network settings, test other online games.
• If problem remains, try a different profile or offline->online switch and check server status.

Mobile (Android / iOS)
• Force-stop app, clear app cache (Android) or Offload App (iOS), then reopen.
• Reinstall the app, ensure OS is up to date, grant network permissions, and try mobile data vs Wi-Fi.
• Turn off battery saver or background restrictions.

Account & Server checks
• Check official server status / socials for outages.
• Try another account (to rule out account bans/auth issues).
• If servers are fine and local fixes fail, gather logs/screenshots.

What to send to support
Platform, exact error (Code 4), time(s) it happened, short list of steps you tried, screenshots, and game logs or system specs (OS, GPU, drivers). That speeds up a fix.

Marvel Rivals Error Code 4 means a connection issue. Fix it by checking server status, restarting your device and router, ensuring a stable internet, disabling VPN/proxy, and reinstalling the game if needed.

Haha, Error Code 4 again? Essentially the game is telling you, Nope, not today, buddy. Try the standard measures, give a restart to the device, check your Internet, perhaps bribe the router with cookies, clear up your cache, and in case that is also not working, re-install the game. And since it is on you, go to support, all you can do.

Marvel Rivals Error Code 4 refers to an upgrade on the internet connection. The upgrade can be achieved through few easy steps where the player can check for the server issues, rebooting of the router and the device, checking for the internet speed, removing the VPN/proxy connections, and reinstalling the game if the issue still persists.
