Gameloop Error Code 21 is one of those frustrating hiccups that pop up during installation or updating, and honestly, it feels like your PC is just saying “nope” to the connection. Usually, it’s some kind of regional restriction or ISP block messing with the connection, or maybe your antivirus software is throwing a fit and blocking stuff it shouldn’t. Whatever the cause, fixing it isn’t always straightforward, but a few tricks can usually get things back on track.
How to Fix Gameloop Error Code 21
Use a VPN to Bypass Regional Restrictions
This one’s kind of obvious, but hey, sometimes region-based restrictions are the culprit. When Gameloop can’t connect to its servers, switching your IP via a VPN can do wonders. It’s like telling the internet “Hey, I’m somewhere else now!” and suddenly things become accessible again. It’s especially helpful if you’re stuck in a country with strict firewalls or if your ISP is blocking certain endpoints.
On some setups, the VPN proof of concept worked on the very first try, on others more restart/connection toggling might be needed. If you don’t have one, grab a decent VPN like ProtonVPN, NordVPN, or ExpressVPN. Connect to a country where Gameloop’s servers aren’t blocked—think the US or Europe—and then restart Gameloop. Fingers crossed, the error clears up.
Use the Incognito Mode in Your Browser
This is more about cleaning things up from the browser side. Sometimes, cached data, cookies, or outdated sessions mess with the downloader or installer, resulting in failed connections or corrupt downloads. Incognito mode keeps things fresh—no saved cookies, no cached redirects, just a clean slate for whatever Gameloop website needs to do.
Open Chrome or your preferred browser, hit Ctrl + Shift + N (or menu > New Incognito Window), then go to the official Gameloop website. Try the install or update again. On some occasions, this oddly helps, maybe because it bypasses some browser cache or cookie hiccup that was blocking the connection.
Perform a Network Reset from Command Prompt
This is kind of a brutal fix, but resetting network settings often solves deep misconfigurations. Because of course, Windows has to make it harder than necessary — DNS cache corruption or wrong IP settings can block Gameloop from reaching the servers.
Fire up Command Prompt as administrator (search for cmd, right-click, Run as administrator).Then paste and run these commands one at a time, hitting Enter after each:
netsh winsock reset netsh int ip reset ipconfig /release ipconfig /renew ipconfig /flushdns
After all that, restart your PC. Then open Gameloop again and see if the error still shows up. Usually, this clears up some network misconfigurations.
Disable Third-Party Antivirus Temporarily
Antivirus programs are supposed to protect, but sometimes they get overzealous and block legit installers or network connections. If you suspect your antivirus might be causing the problem, disable it temporarily to test. Usually, there’s an icon in the system tray, right-click, and pick options like Disable, Pause Protection, or similar. Make sure to turn it back on afterward.
Once disabled, run Gameloop again and see if Error Code 21 disappears. If it does, then you know your antivirus was the culprit, and maybe you just need to add Gameloop to the exceptions list in your security software.
And if none of this works, as a last ditch effort, switching browsers can sometimes fix the weird, browser-specific issues messing with the download or installer. Use a fresh browser profile—clear cache or cookies—and try again. Because, apparently, Windows has to make everything just a little more complicated.
Summary
- Try a VPN to bypass regional restrictions.
- Use browser Incognito mode to avoid cache/ cookie conflicts.
- Reset your network settings via Command Prompt, then reboot.
- Temporarily disable your antivirus software to test if it’s blocking stuff.
- Switch browsers if the issue persists or suspect browser-related problems.
Wrap-up
Honestly, fixing Error Code 21 can feel like chasing ghosts, but these steps cover the most common causes and solutions. Sometimes, it’s just a matter of toggling a setting, and other times a restart or network reset does the trick. No one method is foolproof, but with a bit of trial and error, it’s usually fixable. Hopefully, this shaves off a few hours for someone, and you’re back to gaming sooner rather than later.
