“Error Code 270” in Marvel Rivals is generally a connection / server issue — the game client is failing to properly connect to the game servers. Uninstall and reinstall Marvel Rivals to ensure a clean install.
Here are several fixes you can try:
🛠 Troubleshooting steps for Error Code 270
Check server status / maintenance
Sometimes the game servers are down or undergoing maintenance after updates. If that’s the case, there’s nothing you can do except wait.
Restart your router / modem and device
Power cycle your network equipment and your PC / console to clear transient network issues.
Switch between wired / wireless connection
If you’re on Wi-Fi, try using Ethernet (wired) to get a more stable connection.
Change DNS settings
Use public DNS servers like Google (8.8.8.8 / 8.8.4.4) or Cloudflare (1.1.1.1 / 1.0.0.1) instead of your ISP’s default.
Flush DNS / renew IP (on PC)
In Windows, run in Command Prompt (as admin):
Then restart the PC.
Disable VPNs, proxies, firewall, antivirus (temporarily)
These can interfere with the game’s connection to servers. If disabling works, add the game (and its launcher) as exceptions.
Clear launcher or game cache
The cached data in the game or launcher might be obsolete or corrupt. Clearing it can help
Verify / repair game files
If any files are corrupted or missing, this can break connectivity. Use the game platform’s “verify integrity” or “repair” option
Retry logging in / “spam” the login button
Many players report that repeatedly trying to log in (or repeatedly pressing the confirmation / “retry” button) eventually works.
Reinstall the game
As a last resort, uninstall and reinstall Marvel Rivals to ensure a clean install
Contact support
If none of the above resolves it, reach out to Marvel Rivals / NetEase support. Provide them your platform, when the error appears, and what steps you’ve already tried.
