Step-by-Step Fixes: Marvel Rivals Error Code 5

Before you begin: Restart your PC and router once. This simple action can fix temporary glitches.

1. Run Steam as Administrator

1. Close Steam completely.
2. Right-click the Steam shortcut on your desktop or Start Menu.
3. Select Properties.
4. Click the Compatibility tab.
5. Check Run this program as an administrator.
6. Click Apply, then OK.
7. Reopen Steam, then launch Marvel Rivals.

This ensures the game has all required permissions.

2. Verify Game File Integrity via Steam

1. Open Steam and go to the Library.
2. Right-click on Marvel Rivals and select Properties.
3. Go to the Installed Files tab.
4. Click Verify integrity of game files.

Wait for the scan to complete. Steam will automatically fix missing or corrupted files.

3. Flush and Renew DNS via Command Prompt

• Press Windows + S, type cmd.
• Right-click on Command Prompt > Run as administrator.
• Type each of the following commands, one by one, and press Enter after each:

ipconfig /release  
ipconfig /renew  
ipconfig /flushdns  
ipconfig /registerdns  

• Restart your PC, launch Steam, and try again.

This resets your IP and DNS settings, which often resolves network-related errors.

4. Change to Google Public DNS

1. Press Windows + R, type ncpa.cpl, and press Enter.
2. Right-click your active network adapter → Properties.
3. Select Internet Protocol Version 4 (TCP/IPv4) → Click Properties.
4. Check Use the following DNS server addresses.
5. Enter:
   • Preferred DNS: 8.8.8.8
   • Alternate DNS: 8.8.4.4
6. Check Validate settings upon exit → Click OK.

5. Sync Your PC Time and Time Zone

1. Press Windows + I to open Settings.
2. Navigate to Time & language > Date & time.
3. Enable:
   • Set time automatically
   • Set time zone automatically
4. Click Sync now.

An incorrect system clock can prevent Steam from verifying your connection.

6. Whitelist Marvel Rivals in Windows Firewall

• Press Windows + S, type Windows Defender Firewall, and open it.
• Click Allow an app or feature through Windows Defender Firewall.
• Click Change settings.
• Click Allow another app → Browse to:

C:\Program Files (x86)\Steam\steamapps\common\MarvelRivals  

• Select the Marvel Rivals executable (.exe).
• Click Add, then check both Private and Public boxes.
• Click OK to save.

7. Clear Marvel Rivals Launcher Cache

1. Launch Marvel Rivals Launcher.
2. Look for settings icon or options menu.
3. Use the “Clear Redundant Files” and “Clear Local Config Files” options.
4. Restart the game.

Multiple users confirmed this helped bypass the login freeze.

8. Disable Discord or Other Overlays

1. Open Discord.
2. Go to User Settings > Game Overlay.
3. Turn off Enable in-game overlay.

Overlay conflicts can interfere with game login processes.

9. Use a Gaming VPN (Optional)

If your region or network has connection issues:

1. Download a VPN like ProtonVPN or ExpressVPN.
2. Connect to a stable server region (preferably close to game servers).
3. Launch Steam and try again.

10. Reinstall Marvel Rivals

If nothing else works:

1. Press Windows + R, type appwiz.cpl, press Enter.
2. Select Marvel Rivals → Click Uninstall.
