2XKO Error 2001: How to Fix 2XKO 2001 Failed to Log In Error?

2XKO Error 2001: What’s Actually Going On?

This error means, well, the game can’t log you in. Seems simple, right? But under the hood, it’s usually a mix of server overload, leftover beta cruft, or some completely random software shenanigans that make your login request go poof into the digital void.

One evening last week, I fired up 2XKO, thinking I’d get in a couple rounds before dinner en boom, the “Failed to log in (2001)” message slapped me upside the head. Turns out I wasn’t the only one. The Discord was blowing up, and Reddit looked like a support group for the “2001 error-affected” out there.

You know, it’s like when you’re finally ready to watch your favorite show and your streaming app says, “network error.” Same energy.

The Fastest Fix

Just uninstall and reinstall 2XKO after fully closing the Riot Client.

Before you roll your eyes and say, “I’ve done that a hundred times,” consider this: a ton of folks who played the closed beta or fiddled with alpha builds are running into this leftover cache problem. It’s that classic “the game thinks you exist in a parallel universe” bug.

Here’s the best step-by-step rundown:

  • Shut down the Riot Client from your system tray. Not just clicking “close”—make sure it’s properly, totally exited.

  • Go to Windows Settings > Apps, find 2XKO, and uninstall it.

  • Restart your trusty PC. (We know, the good ol’ magic trick. Still works!)

  • Re-download 2XKO from Riot Client and reinstall.

  • While you’re waiting, stretch. Or just mutter angrily about servers to nobody in particular.

It genuinely worked for most of us after battling the error—with a little side of humble pie. I’ll admit, I once reinstalled it three times before realizing I wasn’t killing the Riot Client properly. You live and learn.

The Wild World of Internet and Firewall Fixes

I’ve seen fixes like starting Vanguard’s VGC service in Windows, running a bunch of command prompt codes, or even changing your DNS to Google’s 8.8.8.8. It all sounds very “IT help desk,” and, if we’re honest, a little more dramatic than most people want when all you want is to punch pixel brawlers.

  • Restart modem and router (especially with VPN weirdness).

  • Run network reset codes in admin Command Prompt:

    • ipconfig /release

    • ipconfig /flushdns

    • ipconfig /renew

    • netsh int ip reset

    • netsh winsock reset

  • Make sure VGC (Vanguard) is set to “Automatic” in Windows Services, and give the game firewall permissions.

  • One player swore up and down that uninstalling Citrix Workspace magically fixed the issue. Was Citrix angry about you fighting game characters? Who knows.

Sometimes, you just have to laugh at how ridiculously specific these solutions can be.

At the risk of sounding like Riot’s official support bot: If nothing works, it’s probably just the server load. Riot themselves jumped onto X (Twitter? Whatever it’s called now) saying they’re working on a fix, and that patience will win out in most cases.

So, don’t beat yourself up if you try all the fancy troubleshooting and the error still hangs around. Sometimes it really is “not you, it’s them.”
If all else fails, leave the launcher alone and check in after a snack break, a walk, or a doom scroll through social media. You might be surprised when you come back and it magically works.

Bonus: Real Players, Real Fixes

  • Some said resetting their router for a new IP sorted everything.

  • Others found deleting the “Lion” and any 2XKO folders from their AppData cleared up lingering ghosts from past installs.

  • A few got lucky just retrying after 10–15 minutes—servers chill out, and the chaos passes.

Last Thoughts 

Look, error 2001 is frustrating. It’s basically a tech hiccup that hits just when you want to relax with your favorite game. The fixes above aren’t guaranteed magic, but they’ve helped a lot of folks—including some who nearly rage-uninstalled everything from their PC.

One day, maybe these logins will “just work.” Until then, remember: take breaks, laugh at the weirdness, and maybe have another go in half an hour.
And, if you ever figure out why Citrix Workspace sometimes stops a fighting game from logging in… write a book. I’d buy it.
