You're seconds away from entering your favorite game and, suddenly, a gray box with a number inside appears. No explanation, no context, just a code. It's one of the most frustrating situations on the platform, especially because the message rarely says what actually happened.
The good news is that most Roblox error codes aren't mysterious at all. Each one points to a specific area: your internet connection, Roblox servers, your account, the application installation, or a ban applied within a specific game. Once you understand which category your code falls into, the solution usually takes less than five minutes.
In this guide you'll find the codes that players most frequently encounter, what each one means in practice, and the solutions that actually work, whether on PC, mobile, Xbox, or browser. We've also corrected some misinformation circulating about two of the most common codes.
Before you look for your code, try this.
There are a set of basic steps that resolve a good portion of Roblox errors, regardless of the number displayed on the screen. The first is the most obvious and most forgotten: check if Roblox is down. If the platform is experiencing a widespread outage, there's nothing you can do on your end. Check the official Roblox status page or look on social media for reports from other players in the last hour.
The second step is to completely close Roblox and then reopen it. Minimizing it isn't enough. On Windows, open Task Manager and end any processes. RobloxPlayerBeta.exe That's running. On a Mac, force quit via the menu. On a mobile phone, swipe the application out of the recent apps menu. After that, restart the router: unplug it from the power source for 30 seconds. This simple action resolves a surprising number of disconnection errors.
Finally, try another game. If only one game fails and everything else loads normally, the problem is with that game, not your connection. And if none of this works, update or reinstall Roblox, because an outdated client generates connection failures that look like server problems but aren't.
Errors 277 and 279: You lost connection to the server.
Error 277 appears when Roblox cuts your session mid-game. Common causes include an unstable Wi-Fi connection, packet loss, or a device switching networks in the background without your knowledge. Error 279 is practically the same, but it occurs while you're entering the game instead of during gameplay.
To resolve error 277, move closer to your router or switch to a wired connection, which is always more stable. Run a speed test: Roblox recommends at least 4 to 8 Mbps. Disable any VPN or proxy you have running, as these are among the most frequent causes of this error. If you use antivirus software, try temporarily disabling it and then logging back in. If that works, add Roblox as an exception instead of leaving the protection disabled.
In the case of version 279, the focus should be on the firewall and security software. On Windows, allow Roblox through Windows Defender Firewall in Settings, Privacy & Security, Windows Security, Firewall & network protection, Allow an app. You can also change the DNS to a public server like 1.1.1.1 or 8.8.8.8, which usually resolves persistent connection issues. If you use Roblox in a browser, disable extensions, especially recently installed ad blockers or script blockers.
Here's a quick way to see if the problem is with your network: connect your phone to mobile data and try logging in through that method. If it works, the problem is with your home internet connection and not your account.
Errors 266 and 524: the connection timed out.
Error 266 means that Roblox waited for a response from your device and never received it. In practice, it's the same type of problem as error 277 and is resolved in the same way, focusing on network stability and eliminating intermediaries such as VPNs.
Error 524 is more specific and often appears when you try to join a private or VIP server that you don't have access to. Before assuming it's a technical problem, confirm that you actually have permission to join that server and ask the owner to resend the invitation link, because these links expire.
If error 524 appears in a public game, then it's a matter of server response time. Wait a few minutes and try again, or choose a different server for the same experience. Full servers or those under heavy load frequently return this error in games that have just received a major update.
Errors 267 and 600: You have been banned from an experiment.
This is where the most misinformation circulates online, so it's important to clarify. Error 267 means that the creator of that experience banned your account for violating the Community Guidelines within their game. The ban doesn't come from Roblox, it comes from the developer, and your account continues to function normally across the rest of the platform.
Error 600 is exactly the same thing. You'll find several websites saying it's an IP ban, but that's false: the official Roblox documentation describes 600 as a ban applied by the experience creator, just like 267. If you encountered this code, you're not banned from Roblox, you're banned from a specific game.
The downside is that you can't appeal these bans through Roblox Support. Support doesn't have the authority to remove bans applied by creators, nor do they contact them on your behalf. The only way is to speak directly with the developer, either by messaging them on Roblox, through the group's community wall, or through any social media accounts linked to their profile or the experience page.
It's worth trying even if you think you haven't done anything wrong. Many games use automatic anti-cheat systems that produce false positives, and developers regularly reverse these bans when someone explains the situation politely.
How to clear the Roblox cache
Several of the steps above mention clearing the cache, so here's the exact process for each system. On Windows, press the Windows key + R, type %localappdata%\Roblox and confirm. Inside that folder, delete the contents of the folders. logs and LocalStorage, but never the Roblox folder itself.
On a Mac, open Finder, press Cmd + Shift + G, and type ~/Library/Caches/ and remove the Roblox folder that you find there.
On Android, go to Settings, Applications, Roblox, Storage and tap Clear cache. This option doesn't exist on iOS, so the alternative is to use the app's download function in the storage settings or simply reinstall it.
Conclusion
If you've already tried everything in this guide and the error persists, the next step is to contact Roblox Support with the exact code, the platform you're using, and a screenshot of the message.
The more specific the information you send, the faster the response. The exception remains errors 267 and 600, where support can do nothing and the solution necessarily goes through the game creator.
