If you’re stuck staring at the pesky Marvel Rivals error code 211 every time you try to launch the game, fret not, as this guide covers everything you need to know to fix it, from what’s causing the issue to the most upvoted workarounds.
While some Marvel Rivals error codes can feel like a piece of work, most are easy to deal with once you know what’s triggering them. Luckily, error code 211 falls into that second category, but with a bit of a catch: there are multiple workarounds, and not all of them may work for your situation. It might take a bit of trial and error to figure out which fix actually does the trick. So, without further delay, let’s get you back into your favorite NetEase hero shooter, shall we?
Marvel Rivals error code 211 cause and fixes

The error code 211 in Marvel Rivals indicates a connection error specific to Steam. So, you’re only likely to face this hiccup if you’re playing the game on a PC. Now that you know why your crossplay duo is able to log in while you continue to struggle, here are the fixes you should try for the Marvel Rivals error code 211 to quickly rejoin the grind.
Check server status and your internet connection
Before you go on to try the relatively complicated workarounds, make sure you aren’t trying to log in at a time when the developers are in the process of deploying a patch or conducting a server maintenance. The error code 211 may be caused by both client and server-side factors, so it’s wise to check the official social pages to confirm if there’s a server outage or not before you waste your time trying other fixes.
At the same time, make sure your internet connection is working fine. Check if rebooting your router and modem, or switching to a direct (ethernet) connection helps. Make sure you’re not connected to a VPN or server blockers.
Exit Steam and relaunch it
If you’ve recently changed your login username or password on Steam, but chose to remain logged in on your PC, NetEase is probably struggling to authenticate your account, hence the error code 211. Try logging out of Steam. Close Steam and then relaunch it. Sign in with your new credentials and then try launching Marvel Rivals.
Verify integrity of game files
Open your Steam library and select Marvel Rivals to open its page. On the right side, click on the cog icon and then Properties. Under the Installed Files tab, click on Verify integrity of game files. Let the process complete, and then try to launch the game.
Allow Marvel Rivals through firewall
If you use Windows Defender as your primary anti-virus, make sure the game and Steam is allowed through the firewall. To check, open the Control Panel app on your PC, go to System and Security > Windows Defender Firewall, and then select Allow an app or feature through Windows Defender Firewall. Make sure Marvel Rivals and Steam are enabled for both Public and Private options.
If none of these workarounds work for you, the Marvel Rivals error code 211 probably indicates a more complicated connection issue. We recommend waiting an hour or two to rule out internal hiccups, after which you can drop NetEase a support ticket for further help.
