🎮 Game Error Codes What it means & how to fix it

Marvel Rivals Error Codes

Most Marvel Rivals error codes are NetEase server or connection problems, with a few tied to specific platforms (PlayStation, Xbox). Here's what each common code means and how to clear it.

Error codes

2100 Connection error — can't reach the servers

Cause: The client failed to connect to NetEase's servers, usually server load, maintenance, or a local network drop.

Fix:
  1. Check the Marvel Rivals server status / official X before troubleshooting.
  2. Restart your router and use a wired connection.
  3. Fully restart the game and relaunch.
220 Login / authentication error

Cause: The client couldn't complete NetEase account authentication at sign-in — usually a rerouted connection (VPN/proxy), an unstable network, or a bad login session.

Fix:
  1. Fully close Marvel Rivals and restart your PC to clear a stuck login session.
  2. Turn off any VPN or proxy — authentication frequently fails when traffic is rerouted through another region.
  3. Switch to a wired connection or restart your router to remove packet instability before re-logging in.
  4. Make sure your firewall/antivirus is not blocking Marvel Rivals; move it to the allowed list.
  5. Flush DNS (ipconfig /flushdns), restart, then sign in again.
270 General client-side error

Cause: A catch-all client fault — corrupted or missing game files, a broken session, or security software interrupting the connection/login check.

Fix:
  1. Verify/repair the game files in your launcher (Steam, Epic, or the Marvel Rivals launcher) to replace corrupted files.
  2. Restart the game and PC to clear a temporary bad session.
  3. Disable VPN/proxy and confirm a stable connection before relaunching.
  4. Whitelist Marvel Rivals in your firewall and antivirus.
  5. If it persists after a verify, reinstall the game to a clean state.
10 (also shown as 5-...) Server-side error

Cause: A general server or matchmaking problem on NetEase's side, most common right after a patch.

Fix:
  1. Wait and retry — it's usually server-side and clears on its own.
  2. Restart the game.
  3. Confirm servers are up before changing local settings.
4 Connectivity error (common on PlayStation)

Cause: A weak or unstable connection between your PS5 and the servers.

Fix:
  1. Restart your router; test your PSN connection in Settings.
  2. Switch to a wired connection.
  3. Rebuild the PS5 database if disconnects persist.
6 Network / disconnect error

Cause: Your connection to the match dropped mid-session, often packet loss or a router hiccup.

Fix:
  1. Use a wired Ethernet connection.
  2. Stop other downloads and streams on the network.
  3. Restart the router if packet loss continues.
11 Failed to connect to the game session

Cause: A matchmaking/session handshake failed, common during high load or after an update.

Fix:
  1. Restart the game so your session re-registers.
  2. Retry from the main menu.
  3. Check for a game update and install it.
21 Network problem (common on Xbox)

Cause: An Xbox network or NAT issue reaching the servers.

Fix:
  1. Test your Xbox network connection in Settings.
  2. Set your NAT to Open (enable UPnP on the router).
  3. Restart the console and router.
1001 Login / authentication error

Cause: The login service couldn't verify your account, sometimes a linked-account or server-auth glitch.

Fix:
  1. Restart the game and log in again.
  2. Check the NetEase/Marvel Rivals login service status.
  3. Re-link your platform account if it repeats.

Fixes that work for most Marvel Rivals errors

  1. Check the game's official server status page or its X/Twitter/Discord — if servers are down or under maintenance, no local fix will help; wait it out.
  2. Fully close and restart the game and its launcher (Steam / Epic / EA App / PlayStation / Xbox) via Task Manager, not just the in-game menu.
  3. Restart your router and, on PC, flush DNS (open Command Prompt and run: ipconfig /flushdns).
  4. Verify or repair the game files in your launcher so a corrupted update is re-downloaded.
  5. Make sure the game and your OS are fully updated — most 'version mismatch' errors are an out-of-date client.
