Servicenow ui-component deploy not working

I am creating a custom UI component for UI Builder. I have successfully setup the project.

But while trying to deploy the component using "snc ui-component deploy" I am getting error that "Could not find an active connection to a ServiceNow instance."

Service now account is open and running in my default browser. I even tried to create a named profile and deploy as below

snc ui-component deploy --profile profile-name

But it still gives me same error i.e. "Could not find an active connection to a ServiceNow instance."

ServiceNow version is San Diego

What possible issue this could be?

Know someone who can answer?
