Controller connectivity is lost after you upgrade your hosts.

Problem

After upgrading your host, when running post checks, your Node Status shows loss of connectivity to the controller.

Solution

  • In the NSX Manager CLI, run the following command to push the host certificate to the Management Plane:
    push host-certificate <hostname-or-ip-address[:port]> username <username> thumbprint <thumbprint>
    Use the user name and password for the NSX Manager. See the NSX-T Data Center Command-Line Interface Reference for more information.
