Local issuer certificate error when attempting to use kubernetes schema

hi Team,
I installed the yaml extension and also added the yaml schema as below.

{
    "git.autofetch": true,
    "git.suggestSmartCommit": false,
    "team.showWelcomeMessage": false,
    "explorer.confirmDelete": false,
    "terminal.integrated.shell.windows": "C:\\Program Files\\Git\\bin\\bash.exe",
    "yaml.schemas": {
        "kubernetes": "*.yaml"
    }
}

However i am not seeing the extension doing the autocomplete/suggestion. I am seeing below error though:

Unable to load schema from 'https://raw.githubusercontent.com/instrumenta/kubernetes-json-schema/master/v1.17.0-standalone-strict/all.json': unable to get local issuer certificate.

Start by reproducing the schema load from the URL in the yaml.schemas setting and inspect the reported local issuer certificate error. The issue mentions no repository file or test; done means the Kubernetes schema loads successfully and autocomplete or suggestions work.
