  • Hi,

    Please run slui 4 to get the telephone activation wizard and activated the machine over the phone system.

    More details about this error:

    This issue may occur when you connect to the Internet through a proxy server where Basic authentication is enabled.

    When the proxy server is configured for Basic authentication, the server requires that you type a username and a password. However, the activation user interface does not let you enter these credentials. Therefore, the Basic authentication fails, and activation is not successful.

    Please try the following methods: 
    Method 1: Configure the proxy server to disable Basic authentication
    Method 2: Configure your proxy server to exclude the URLs for the certificate revocation lists (CRLs) from the requirement for Basic authentication
