Cannot connect to a server

Use this information to resolve the issue when you cannot establish a remote-control session with a server.

Complete the following steps to resolve this issue.
  • Ensure that you have lxc-supervisor, lxc-admin, lxc-security-admin, lxc-fw-admin, lxc-os-admin, lxc-hw-admin, lxc-service-admin, or lxc-hw-manager privileges.
  • Ensure that your local system has network connectivity and that it can connect to Lenovo XClarity Administrator.
  • Ensure that the server is being managed by XClarity Administrator by clicking Hardware > Servers from the XClarity Administrator menu bar.
  • If a firewall is installed on your local system, ensure that the firewall allows connections to the IP address for the managed server.
  • Ping the IP address of the managed server to ensure that your local system has connectivity to the managed server. If you are attempting to access a managed server from a local system that has an IP address from an external network, the managed server must also have an IP address that can be accessed externally.
  • Ensure that XClarity Administrator tunneling has not been disabled so that XClarity Administrator can tunnel your remote-control requests to the managed server that is network addressable only on the private management network. Tunneling is enabled by default.

    You can enable XClarity Administrator tunneling from the remote-support Preferences dialog on the Security tab. For more information, see Setting remote-control preferences.
