How to Fix GitHub Code Expired Sign-In Loop in Microsoft Scout

Microsoft Scout is an AI-powered desktop assistant that integrates with various services, including GitHub, to help developers search code, analyze repositories, and streamline development workflows. During the initial setup or while reconnecting your GitHub account, Scout may ask you to complete the GitHub Device Authorization flow. However, some users encounter a frustrating issue where Scout repeatedly displays a “Code Expired” message, forcing them into an endless sign-in loop without successfully linking their GitHub account.

The GitHub Code Expired sign-in loop usually occurs when the device authorization code expires before it’s verified, the browser session is using the wrong GitHub account, cached authentication tokens become corrupted, system time is incorrect, network restrictions interfere with the authentication process, or Scout is running an outdated version. In enterprise environments, GitHub organization policies or browser extensions can also interrupt the authentication process.

Fortunately, there are several ways to resolve the issue and successfully sign in to GitHub from Microsoft Scout. In this guide, we’ll show you how to fix the GitHub Code Expired Sign-In Loop in Microsoft Scout on Windows 11.

How to Fix the GitHub Code Expired Sign-In Loop in Microsoft Scout

Follow the methods below in order. After completing each one, try signing in to GitHub again.

1. Generate a New Sign-In Code

GitHub device authorization codes are valid only for a limited time.

To avoid expiration:

1. Close the current sign-in window in Microsoft Scout.
2. Start the GitHub sign-in process again.
3. Copy the newly generated device code.
4. Immediately open the GitHub verification page.
5. Enter the new code and complete the authorization without delay.

If the previous code has expired, only a newly generated code will work.

2. Verify You’re Signing In to the Correct GitHub Account

Using a different GitHub account in your browser may cause the authorization process to fail.

1. Open GitHub in your web browser.
2. Confirm which account is currently signed in.
3. Sign out if necessary.
4. Sign in using the account you want to connect with Microsoft Scout.
5. Retry the authorization process.

Using the correct account prevents authorization conflicts.

3. Use an Incognito or Private Browsing Window

Browser cookies or cached sessions may interfere with GitHub authentication.

To test this:

1. Open an Incognito or Private window.
2. Visit the GitHub device verification page.
3. Sign in with your GitHub account.
4. Enter the new device code.
5. Complete the authorization.

A private browsing session eliminates cached authentication data.

4. Synchronize Your System Date and Time

Incorrect system time can cause authentication tokens to appear expired.

1. Open Settings > Time & language > Date & time.
2. Enable Set time automatically.
3. Enable Set time zone automatically if available.
4. Click Sync now.
5. Restart Microsoft Scout.

Accurate system time is essential for secure authentication.

5. Restart Microsoft Scout

Temporary authentication glitches may cause repeated sign-in attempts.

1. Close Microsoft Scout completely.
2. Open Task Manager (Ctrl + Shift + Esc).
3. End any remaining Scout-related processes.
4. Launch Microsoft Scout again.
5. Retry the GitHub sign-in.

Restarting the application refreshes the authentication workflow.

6. Clear Scout’s Authentication Cache

Corrupted cached credentials may repeatedly trigger the sign-in process.

1. Close Microsoft Scout.
2. Navigate to Scout’s local data or cache folder.
3. Delete or rename the authentication cache files.
4. Restart Scout.
5. Sign in to GitHub again.

Scout will create fresh authentication data during the next login.

7. Remove Existing GitHub Authorization

Previously stored authorization tokens may have become invalid.

To revoke and reconnect:

1. Open your GitHub Account Settings.
2. Navigate to Applications.
3. Locate the authorization for Microsoft Scout.
4. Revoke the existing authorization.
5. Return to Scout and begin the sign-in process again.

Creating a fresh authorization often resolves persistent login loops.

8. Disable VPN or Proxy Services

VPNs, proxies, or filtered networks may interrupt communication with GitHub.

1. Disconnect your VPN.
2. Disable any manual proxy settings.
3. Restart Microsoft Scout.
4. Generate a new GitHub device code.
5. Complete the sign-in again.

If the issue disappears, configure your VPN to allow GitHub authentication traffic.

9. Update Microsoft Scout

Older versions of Scout may contain authentication bugs.

1. Check whether a newer version of Microsoft Scout is available.
2. Install the latest update.
3. Restart your computer if prompted.
4. Launch Scout again.
5. Retry the GitHub sign-in process.

Software updates frequently include fixes for authentication issues.

10. Update Your Default Web Browser

Outdated browsers may fail to complete modern authentication flows.

1. Open your preferred browser.
2. Install any available updates.
3. Restart the browser.
4. Generate a new GitHub code.
5. Complete the authorization.

Keeping your browser updated ensures compatibility with GitHub’s latest authentication methods.

11. Check Firewall or Security Software

Security software may block authentication requests between Scout and GitHub.

1. Temporarily disable third-party firewall or antivirus software.
2. Ensure Microsoft Scout is allowed through Windows Firewall.
3. Retry the sign-in process.
4. Re-enable your security software after testing.

If the issue is resolved, add Scout to your firewall’s allow list.

12. Reinstall Microsoft Scout

If authentication files are corrupted, reinstalling the application may resolve the problem.

1. Open Settings > Apps > Installed apps.
2. Uninstall Microsoft Scout.
3. Restart your computer.
4. Install the latest version of Scout.
5. Launch the application and reconnect your GitHub account.

A clean installation replaces damaged files and resets authentication settings.

Conclusion

The GitHub Code Expired Sign-In Loop in Microsoft Scout is typically caused by expired device authorization codes, cached authentication data, incorrect browser sessions, network restrictions, or outdated software. In most cases, generating a new code, signing in with the correct GitHub account, using a private browsing window, or clearing Scout’s authentication cache is enough to resolve the issue.

If the problem continues, revoke the existing GitHub authorization, update Microsoft Scout and your browser, verify your system time, and reinstall Scout if necessary. By following the troubleshooting methods in this guide, you should be able to successfully link your GitHub account and eliminate the repeated “Code Expired” sign-in loop.
