Marvel Rivals Error Codes Guide: Fixes

Marvel Rivals error codes are network, server, or client messages that stop you from joining a match or staying connected. This guide explains the most common codes, what they mean, and the exact steps to fix them on PC and console.

What Are Marvel Rivals Error Codes?

Marvel Rivals is a free-to-play hero shooter that requires a constant connection to its servers. Error codes appear when the game cannot establish or maintain that connection, when your client version doesn’t match the server, or when your hardware/driver can’t handle the game. They are not random – each code points to a specific layer of the connection chain.

Most codes fall into one of three categories:

Network errors – your internet, router, or the game’s servers are the problem.
Server errors – the game’s backend is down or under maintenance.
Client errors – your game files, drivers, or system are out of date or corrupted.

Common Error Codes and Their Meanings

Here are the codes players most frequently encounter, with what each one actually tells you.

Error 1 (or “Unable to Connect”) – The game cannot reach the login or matchmaking server. Usually your internet connection or the game’s servers are at fault.
Error 2 (or “Connection Timed Out”) – The server took too long to respond. Often caused by high ping, packet loss, or a temporary server hiccup.
Error 3 (or “Server Full”) – The server has reached its player cap. Wait a few minutes and retry.
Error 4 (or “Client Out of Date”) – Your game version doesn’t match the server. Update the game through your launcher (Steam, Epic, or console store).
Error 5 (or “Authentication Failed”) – Your login token expired or is invalid. Restart the game and log in again.
Error 6 (or “Anti-Cheat Error”) – The anti-cheat service (like Easy Anti-Cheat) failed to start. Reinstall the anti-cheat or run the game as administrator.

How to Fix Network-Related Errors

If you see a network error (1, 2, or 3), follow these steps in order. Most connection issues are on your side, not the game’s.

Restart your router and modem – Unplug both for 30 seconds, then plug them back in. This clears most temporary network glitches.
Use a wired connection – If you’re on Wi-Fi, switch to an Ethernet cable. It reduces packet loss and latency spikes.
Close bandwidth-heavy apps – Stop downloads, streaming, or cloud backups while playing.
Change your DNS server – In your network settings, set DNS to a public one like Google (8.8.8.8 and 8.8.4.4) or Cloudflare (1.1.1.1). This can fix connection timeouts.
Check the server status – Visit the official Marvel Rivals status page or social media. If servers are down, no fix on your end will work.

How to Fix Client and Anti-Cheat Errors

For errors 4, 5, and 6, the problem is usually your game installation or system.

Update your graphics drivers – Outdated GPU drivers can cause crashes that look like error codes. Download the latest driver from NVIDIA, AMD, or Intel.
Verify game files – In Steam, right-click the game, go to Properties > Installed Files > Verify Integrity. On Epic, click the three dots and select Verify. On consoles, uninstall and reinstall the game.
Reinstall Easy Anti-Cheat – Navigate to the game’s installation folder, find the EasyAntiCheat folder, and run the installer (or repair) as administrator.
Run the game as administrator – Right-click the game’s exe and select “Run as administrator”. This can fix permission issues with anti-cheat.
Disable overlays – Turn off Steam, Discord, or GeForce Experience overlays, as they can interfere with the game’s connection.

What to Do If the Error Persists

If you’ve tried the above and still get the same code, consider these additional steps:

Check for Windows updates – A pending update can cause compatibility issues.
Disable VPN or proxy – VPNs can trigger authentication errors. Turn it off and try again.
Flush DNS and reset Winsock – Open Command Prompt as administrator and run ipconfig /flushdns and netsh winsock reset. Restart your PC.
Contact support – If nothing works, submit a ticket to the official Marvel Rivals support team with a screenshot of the error and your system specs.

Frequently Asked Questions

Q: Why do I keep getting “Error 2” even with a good internet connection?
Error 2 often means the server is overloaded or your connection to that specific server region is poor. Try switching regions in the game settings, or wait a few minutes and retry.

Q: Can I fix error codes by reinstalling the game?
Reinstalling helps with corrupted files (error 4, 6), but not with network or server errors. Try the network fixes first; reinstalling is a last resort.

Q: Are error codes the same on PS5, Xbox, and PC?
The codes are similar, but the fixes differ slightly. On consoles, you can’t verify files or run as administrator – you’ll need to uninstall/reinstall or restart the console.

Q: Does using a VPN cause error codes?
Yes, VPNs can trigger authentication errors (like error 5) because the game sees a different IP than your actual one. Disable the VPN before launching the game.

Q: How long do server maintenance errors last?
Maintenance windows are typically 2–4 hours and are announced in advance on the official Discord and social media. If you see a maintenance error, check those channels for an ETA.

Q: What does “Error 7” mean?
Error 7 isn’t a standard code in Marvel Rivals. If you see it, it’s likely a rare client error – verify files and update drivers. If it persists, report it to support.
