Roblox on Xbox: Error 901 and General Troubleshooting

Updated November 6, 2026

Roblox on Xbox has one recurring error worth knowing — Xbox Error 901 — triggered by username rules at signup or by account/Gamertag linking problems during sign-in. Roblox’s troubleshooting guide for Xbox issues is intentionally short: “If after following the suggestions above, you continue to experience any issue(s), please contact Roblox Customer Support”, with a reference to Microsoft’s Xbox One Support page for hardware-side problems. Error 901 has two distinct causes with different fixes; this guide separates them and covers the broader Xbox troubleshooting flow. Verified on 6 November 2026.

Error 901 at signup

Roblox’s rule for Error 901 during account creation: the issue is almost always with the username you’re trying to pick. Roblox’s username guidelines:

• No inappropriate words or phrases. Roblox’s filter rejects words flagged by its community-standards system.
• No personally identifiable information. First/last names, phone numbers, street names, addresses all trigger the filter.
• 3 to 20 characters. Shorter or longer names are rejected.
• Alphanumeric only. A-Z and 0-9 are allowed; no special characters.
• Maximum one underscore. It cannot be at the beginning or end of the name.

Roblox’s exact wording: “User names should be a minimum of 3 characters and a maximum of 20 characters, use only alphanumeric characters (A-Z, 0-9), and only contain up to one underscore, which is not at the beginning of the end of the name.”

If Error 901 appears at signup, try a different username that fits all five rules. The filter doesn’t tell you which rule you broke — it just rejects the name.

Error 901 at sign-in or Gamertag linking

Roblox’s three-step fix for sign-in Error 901:

1. Log into your Roblox account from a different device on the same home network (computer or phone browser).
2. Once successfully logged in from that device, go back to your Xbox One.
3. Try to sign in on Xbox One using the same home internet network.

This flow forces Roblox to recognize your home network as safe for this account, which clears the sign-in block on Xbox.

When Error 901 means moderation

Roblox’s third cause for Error 901: “The user account connected to your Gamertag is moderated. To review your moderation status, please try logging in on any other device e.g Web browser, Mobile, etc.”

What this means in practice:

• If Error 901 persists after trying both fixes above, your Roblox account may be banned or suspended.
• Log in via a web browser or the mobile app. The ban message will show there with the specific reason.
• If you want to appeal, Roblox provides a support form. Roblox’s warning: “Submitting an appeal does not guarantee your ban will be removed.”

Account moderation is tied to actions taken on any platform — a ban applied on PC blocks Xbox sign-in too.

General Xbox troubleshooting flow

Roblox’s general-issue guide for Xbox One recommends consulting Microsoft’s Xbox One Support page first. The common Xbox-One checklist:

1. Power-cycle the console. Hold the Xbox button on the console for 10 seconds until it fully powers down, wait 30 seconds, then power back on.
2. Check network connection. Xbox Settings → Network → Test network connection. A stable connection is required for Roblox.
3. Verify Xbox Live service status. Microsoft’s Xbox Live status page shows any ongoing platform outages.
4. Clear persistent storage. Settings → Devices & connections → Blu-ray → Persistent storage → Clear persistent storage. This clears cached game data.
5. Uninstall and reinstall Roblox. Highlight Roblox in My games & apps → Menu → Uninstall. Reinstall from Microsoft Store.

Each step takes under 10 minutes; running them in order isolates whether the issue is Roblox-specific or an Xbox-wide problem.

What to send to Roblox support

If troubleshooting doesn’t resolve the issue, Roblox’s support template for Xbox issues:

• Roblox Username.
• Gamertag.
• Any Error Messages Received.
• Any Error Code Received.
• Steps to Encounter the Issue.

Include recent changes to the Xbox account, console settings, or home network. Those details help the support team narrow the cause faster.

Xbox-specific features and limits

Three things to know about Roblox on Xbox:

Xbox players can see other users across platforms in-game and party with them, but cannot redeem Roblox Credit from gift cards on Xbox itself.

Family-accounts linking issues

Some Error 901 reports on Xbox come from family-account-linked Xbox profiles. Three family-specific checks:

1. The parent/manager account must have enabled Roblox access for the child account.
2. The child account’s age setting on Xbox must be at least 13 for full-feature Roblox access.
3. Spending limits on the child account can block Robux purchases — set by the family manager in Xbox settings.

Managed family accounts frequently see login failures from parental-control conflicts rather than Roblox issues.
