  • Hi @CharcoGreen,

    From your output, it seems you are experiencing a timeout on port 443. Is it in use by another application, or is it blocked by a firewall of your OS or a firewall at the infrastructure level?

    The first step would be to determine why your traffic is blocked, and after that, come up with an action plan to fix the issue.


  • Thanks for your help,
    I´m renew my cluster and my firewall rules
