    Error: 'Not able to contact Webex service. A firewall may be blocking the system from connecting.' when Activating a Webex Board
    list-menuFeedback?

     

    You can configure a Cisco Webex board, room, or desk device running RoomOS to use a Proxy server for HTTPS and WebSocket traffic. If the Proxy server requires authentication and you do not provide a username/password or provide a wrong username/password, your device won’t be able to connect to the internet.

    If your device has not been activated yet, the message “Not able to contact Webex service. A firewall may be blocking the system from connecting” appears below the activation code:

    If your device has already been activated, the message “Offline – no internet connection?” appears in the issues and diagnostics menu:

    Log messages – Proxy failure due to 407 Authentication required:
    User-added image

    This is what is seen from the “system logs” web page after enabling extended logging and looking at the file called eventlog/application.log. A 407 Proxy Authentication Required is returned.

    To fix this problem, enter the correct username and password during the proxy configuration:
