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.
