Roblox Error Codes: What They Mean, What to Try

Most Roblox error codes arrive with a vague message and a Leave button, and the help pages behind them are less specific than the numbers suggest. Roblox's help centre keeps a Roblox Error Codes index with eleven numbered codes and one named error, each linked to its own article. We read all twelve on October 13, 2026. The most useful line in each is the short "Why does this happen?" paragraph near the top, because it tells you whether the fix is on your side at all. A reinstall will not lift a ban, and no setting on your phone will get you into a private server you were never added to.

The codes Roblox documents

The index is not the whole set: two platform codes, 292 and Xbox 901, have articles of their own outside it (covered below). For anything else, the index says that if you cannot find your error code or message in its help articles, you should contact its support team.

Six pages, one list of steps

The pages for 264, 266, 268, 277, 279 and 280 describe six different problems, but below the explanation they carry the same troubleshooting steps. We compared the six on October 13, 2026 and the step lists match word for word. For each kind of device the list comes down to a few moves:

• Windows: uninstall Roblox, clear its app data, restart, reinstall. Roblox's app-data step is to uninstall first, press Win+R, type CMD, then run cd AppData\Local followed by rmdir /s Roblox and answer y.
• Mac: move the Roblox app to the Trash and reinstall, and check that Roblox has permission under Privacy & Security.
• iPhone, iPad and Android: restart the device, force-close the app, reinstall it, and make sure the date and time are correct.
• Every device: try a different internet connection, and if the problem stays, contact your internet provider.

So the code itself is the only part of those six pages that changes, and it matters more than the steps do. Reading 264 as a connection fault, for example, sends you through a reinstall when its own explanation points at a second device.

Connection codes: 266, 277, 279 and 268

These four point at the link between your device and Roblox's servers. Roblox's older General Connection Problems article fills in what the per-code pages leave out. It lists an "ID=17 Failure" message among the signs of a connection problem and says the cause is "very frequently a firewall problem", with a low-bandwidth or inconsistent wireless connection behind it in a small number of cases. Its steps, in order:

1. Use an up-to-date browser, or try a different one.
2. Check that your browser's security settings are not set so high that they block Roblox.
3. Switch from wireless to a wired connection if you can.
4. Disable ad-blocking add-ons, which it says can stop a game from fully loading.
5. Keep the ports Roblox uses open: UDP 49152 to 65535.
6. Allow Roblox through your firewall or security software.
7. Reinstall Roblox.

The Error Codes index adds the baseline. Roblox wants an internet speed of 4-8 Mb/s or more, it does not support virtual machines or cloud-based computers (our guide to what devices can play Roblox covers the rest), and it suggests checking whether antivirus or other third-party programs conflict with Roblox. That last point matters most for 268, the one connection code whose explanation names antivirus software. Despite the word "kicked" in its message, nothing in Roblox's article describes 268 as a ban or a moderation action.

264: your account is already in that game

Roblox's explanation for 264 is one sentence: it "occurs when the same account attempts to access the same game from multiple devices simultaneously." The page then gives the shared reinstall list, but the explanation itself points somewhere else: another device signed in to your account, playing the same game. Leave the game on that device and try again.

If no device of yours should be in that game, look at the sessions on your account. How to log out of other devices shows where Roblox lists every signed-in device and how to end them, and how to secure your Roblox account covers the next steps.

280 and 403: your copy of Roblox

Code 280 means Roblox thinks the version on your device is the problem, so the shared steps (update or reinstall) suit it. Code 403 is a PC problem: the app, launched from the website, fails to start. Its page has the Windows reinstall steps plus three for the website on a PC or Mac:

• Clear your temporary internet files and cookies.
• Update your browser.
• Disable active extensions or plugins, and VPNs.

Failed to Load Library: a Windows file problem

This error has a name but no number, and its page has its own causes and steps rather than the shared list. Roblox calls it "a client-side issue, which means the problem is with your device and not with Roblox servers": Roblox cannot reach a Windows system file it needs, often a named one such as MFPlat.dll or urlmon.dll. Roblox's steps, easiest first:

1. Reinstall Roblox. If you use the Microsoft Store version, switch to the desktop version from the Roblox website, or the other way round. Before reinstalling, press Windows key + R, type %localappdata%, and delete the Roblox folder.
2. Repair Windows system files. In an administrator Command Prompt or Windows Terminal, run DISM /Online /Cleanup-Image /RestoreHealth (Roblox says it may take 10-20 minutes), then sfc /scannow, then restart.
3. Install the Media Feature Pack if your Windows is an "N" or "KN" edition, which lacks the media files (MFPlat.dll) Roblox needs. It is under Settings > Apps > Optional features > Add a feature.
4. Check your antivirus for quarantined Roblox files, restore them, and exclude the Roblox folder.
5. Update Windows and your graphics drivers.

If that fails, Roblox asks you to contact support with the exact error message (including any DLL names), your Windows version, and what you have already tried.

267 and 600: a creator's ban, not Roblox's

Codes 267 and 600 have separate articles with the same text. Both say your account "has been banned by the experience creator for violating Roblox Community Standards within their experience", and both add: "This ban is not issued by Roblox. You can still access other experiences and features on the platform." Neither article explains why there are two codes. Whichever one you see, the meaning and the route forward are the same.

What Roblox can and cannot do here is spelled out. Roblox Support "is unable to remove bans issued directly by experience creators or contact them for you", and creators "cannot provide Robux or monetary refunds for purchases made on the Roblox platform." The only route is the creator, who Roblox suggests you reach by:

• sending a message or chatting on Roblox;
• posting on their community wall, if there is one;
• using any social media links on their profile, their community, or the game's details page.

A ban on your Roblox account itself is a different process with its own appeal form, covered in how to appeal a Roblox ban.

524: you were not let in

Code 524 is the one where the fix is most often a setting. Roblox lists four causes: private server settings that are too restrictive, a VIP or private server you have not been invited to, a game or server that is temporarily unavailable, and network or device glitches. It calls the settings "the most common cause":

1. Open Settings: the gear icon at the top right on the website, or More (the three dots) and then the gear in the app.
2. Go to Privacy and content restrictions, then Visibility & private servers.
3. Under Private servers, choose who can add you as a member of their private server.

Roblox adds that users under 13 can only join private servers created by their friends. If the settings are fine, the problem is on the server's side: the owner has to add your username to the "Server Members" list or turn on "Friends Allowed", and a group-only game needs you to join that group first. Our guides on private servers, privacy settings and joining a Roblox group cover each of those screens. If the server is simply down, Roblox suggests waiting a few minutes and checking the game's social media or community pages.

270: only in Roblox Studio

Code 270 is a Studio error. It appears in Roblox Studio when your copy of a place falls out of sync with a Team Create session, and Roblox says it appears on PCs. Its page gives only the Windows reinstall, app-data and network steps. For what Studio and Team Create are, see how to make a Roblox game.

Two codes outside the index: 292 and Xbox 901

292 is a warning rather than a failure. Roblox's Low Memory Warning article, written for the iOS app, says it appears when your device is running low on memory ("this is not a storage space issue") and offers two buttons: Leave, which returns you to the home page, or Keep Playing, with the risk of a crash. Roblox recommends leaving as soon as possible so your progress is saved. If it keeps happening, it suggests closing apps running in the background, lowering the graphics quality, choosing a less demanding game, or using a device with more memory.

Xbox 901 has more than one cause, according to Roblox's Xbox Error 901 article. At sign-up it points to the username: no inappropriate words, no personal information, 3 to 20 characters, letters and numbers only, and at most one underscore, which cannot come first or last. When signing in or linking a Gamertag, Roblox suggests logging in to the account on another device on the same home network, then trying the Xbox again on that network. The third cause is moderation: the account linked to the Gamertag may be moderated, which you can check by logging in on a browser or phone, and which goes through Roblox's appeal process.

Check Roblox's status before you reinstall

A reinstall fixes nothing if the fault is at Roblox's end. Roblox runs a status page at status.roblox.com that reports its website, apps, games, Studio and game joining separately. If game joining shows a problem there, wait rather than troubleshoot. None of the error code articles mention the status page, so this is our suggestion rather than Roblox's.

When nothing works

Roblox's support team is the last stop, and the connection article lists what to send: your Roblox username, any error messages, your device's model name, its OS version, and the steps that lead to the problem, plus any recent changes to your device or network. Support cannot lift a creator's ban (267 or 600). For every other code, those details save a round of back-and-forth.

An error code is a sorting tool before it is a fix. Work out whose side it is on, and the length of the troubleshooting list stops mattering.
