Marvel Rivals Error Code 270 Fix (Login Issue Explained)

Marvel Rivals is a fast-paced 6v6 hero shooter, but some players are blocked at the login screen by Error Code 270. This error usually appears right after major updates or during peak play hours and prevents the game from connecting to the servers.

In most cases, Error Code 270 is not a ban or account problem. It’s a connection failure that happens when your device cannot complete a stable handshake with Marvel Rivals’ servers. The fixes below walk you through the same logical troubleshooting order used to resolve online game login issues—starting simple and moving only as needed.

Step 1: Check Marvel Rivals Server Status

Before changing anything on your system, confirm whether the problem is server-side.

Check official Marvel Rivals channels such as:

• Twitter / X announcements
• Discord server updates
• Downdetector reports

If servers are down or under maintenance, no local fix will work until service stabilizes. Wait a few minutes and try again.

Step 2: Retry Login After a Short Wait

When servers are overloaded, retrying after a brief pause often works.

• Close Marvel Rivals completely
• Wait 2–5 minutes
• Relaunch the game and attempt to log in again

During update periods, multiple retries can succeed once traffic drops slightly.

Step 3: Restart Your System and Internet

If retrying doesn’t help, refresh both your device and network.

1. Shut down your PC or console
2. Unplug your router or modem
3. Wait at least 30 seconds
4. Plug the router back in and wait for full reconnection
5. Restart your system and launch the game

This clears temporary routing and session issues.

Step 4: Switch to a More Stable Connection

Connection quality matters for login authentication.

• Use a wired Ethernet connection if possible
• If already on Ethernet, briefly test Wi-Fi to rule out cable or port issues
• Avoid public or unstable networks

Step 5: Disable VPNs or Proxies

VPNs and proxies can interfere with server authentication.

• Close all VPN software
• Ensure no proxy is enabled in network settings
• Restart Marvel Rivals and try logging in again

Step 6: Change DNS to a Public Provider

DNS issues can prevent proper server resolution.

On Windows:

1. Press Windows + R, type ncpa.cpl, press Enter
2. Right-click your active network → Properties
3. Select Internet Protocol Version 4 (TCP/IPv4) → Properties
4. Choose Use the following DNS server addresses

Use one of the following:

• Google DNS: 8.8.8.8 / 8.8.4.4
• Cloudflare DNS: 1.1.1.1 / 1.0.0.1

Click OK and restart your PC.

Step 7: Flush DNS and Renew IP Address

Clearing cached DNS data can fix hidden connection conflicts.

1. Open Command Prompt as Administrator
2. Run the following commands one by one:

ipconfig /flushdns
ipconfig /release
ipconfig /renew

3. Restart your computer and test the game

Step 8: Clear the Launcher Cache (Steam)

Corrupted cache files can block login requests.

Steam:

1. Open Steam
2. Go to Settings → Downloads
3. Click Clear Download Cache
4. Sign back into Steam and relaunch Marvel Rivals

Step 9: Update Windows and Graphics Drivers

Outdated drivers can cause compatibility issues after game updates.

• Install all pending Windows Updates
• Update your GPU drivers (NVIDIA / AMD / Intel)
• Restart your system after updating

Step 10: Verify Marvel Rivals Game Files

Missing or damaged files can trigger login errors.

1. Open Steam → Library
2. Right-click Marvel Rivals → Properties
3. Go to Installed Files
4. Click Verify integrity of game files

Let Steam complete the scan and apply fixes.

Step 11: Temporarily Disable Firewall or Antivirus

Security software may block the game’s server connection.

1. Open Windows Security
2. Go to Firewall & Network Protection
3. Temporarily disable the firewall
4. Launch Marvel Rivals and test login

If this works:

• Re-enable the firewall
• Add Steam and Marvel Rivals as allowed apps
  Never leave your firewall disabled permanently.

Step 12: Reinstall Marvel Rivals (Last Resort)

If none of the above fixes work:

1. In Steam, right-click Marvel Rivals → Uninstall
2. Restart your PC
3. Reinstall the game
4. Launch and test login
