Error: AADSTS54005: OAuth2 Authorization code was already redeemed

Hello,

I tested Azure Virtual Desktop Quickstart, all days long. When I want to login with Windows App oder Remote Desktop to the VM, I get always the same error: 

--------------------
CAA20003
AADSTS54005: OAuth2 Authorization code was already redeemed, please retry with a new valid code or use an existing refresh token.
--------------------

What's going wrong?

Thank you!

    1. Ensure Single Use of Authorization Code:
    • Authorization codes can only be used once. Make sure your application is not attempting to reuse the same authorization code. Instead, use the refresh token to obtain new access tokens.
    1. Check for Expired Client Secret:
    • Verify that your client secret has not expired. You can do this by navigating to Azure AD > App registrations > Your application > Certificates & secrets. If the secret has expired, create a new one and update your application configuration.
    1. Review Application Code:
    • Ensure your application is correctly handling the OAuth2 flow. After obtaining the authorization code, it should be exchanged for an access token immediately and not reused.
    1. Clear Cache and Retry:
    • Sometimes, clearing the cache or cookies in your browser can help resolve this issue. Try logging in again after clearing the cache.
    1. Use a Different Redirect URI:
    • If you are using a specific redirect URI, ensure it is correctly configured in your Azure AD app registration. Sometimes, using a different redirect URI for testing can help identify if the issue is related to the current URI configuration.
