Roblox error code 273 states “Same account launched from a different device.” This error typically happens when the same Roblox account is used to log in on multiple devices simultaneously. Here’s how to fix it:

1. Check for Active Sessions

• Log out of Roblox on all devices to ensure no duplicate sessions are active.
• To log out:
  1. Go to the Roblox website or app.
  2. Navigate to Settings > Security.
  3. Click Sign Out from All Other Sessions to end all active sessions.

2. Secure Your Account

• If you didn’t start a session on another device, someone else may have access to your account. To secure it:
  1. Change your password immediately via Settings > Account Info > Change Password.
  2. Enable 2-Step Verification in Settings > Security for added security.
  3. Check for any suspicious activity or account changes (e.g., changed email or display name).

3. Wait for Session Expiration

• Roblox sometimes flags lingering active sessions. Wait a few minutes (about 5–10 minutes) before trying to log in again.

4. Clear Cache and Cookies

• Sometimes cached data can cause issues. Clear your browser’s cache and cookies or, if you’re on the app, restart it after clearing its data.
  • For browsers: Go to your browser settings > Privacy > Clear Browsing Data.
  • For mobile devices: Go to Settings > Apps > Roblox > Storage > Clear Cache.

• Make sure you’re not logged into the same Roblox account on another device. If you share your account with family or friends, create separate accounts to prevent conflicts.

6. Check for Hacked or Compromised Accounts

• If someone else has control of your account, contact Roblox Support:
  1. Go to the Roblox Support Page.
  2. Fill out the form with your account details and describe the issue.
  3. Provide proof of account ownership if required.

7. Restart Devices

• Restart your device to refresh the Roblox connection and resolve any potential network conflicts.
