“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.
