Password sync: Troubleshoot Azure AD Connect install issues


Errors in the wizard

The following issues are the most common errors you encounter in the Azure AD Connect installation wizard:

  1. The installation wizard has not been correctly configured

    When the installation wizard hasn't been correctly configured and it cannot reach the proxy, this error appears. Follow these steps to check proxy connectivity.

  2. Unable to validate credentials. An unexpected error has occurred. Unable to connect to the remote server.

    • If this error appears, verify if the machine.config has been correctly configured.
    • If that looks correct, follow these steps to check if the issue is present outside the wizard as well.
  3. The MFA endpoint cannot be reached

    This error appears if the endpoint cannot be reached and your Global Admin has enabled MFA. To prevent this error, verify if the endpoint has been added to the proxy.

  4. The password cannot be verified

    If the installation wizard is successful in connecting to Azure AD, but the password cannot be verified you see this error.

The username or password is incorrect. Verify your username, and then type your password again.
