Connection failed while setting up Initial configuration for SAP HANA Cloud connector

Hi Experts,

I am trying to set up Initial configuration for SAP HANA Cloud connector at (https://localhost:8443/) and connecting to hanatrial.ondemand.com

I get an error saying: Fail to sign the SAP HANA Cloud Connector certificate for account ...verify configuration and proxy settings.

When i checked logs, i can see below entries:

Caused by: org.apache.http.conn.HttpHostConnectException: Connection to https://connectivitycertsigning.hanatrial.ondemand.com:443 refused

When i tried with proxy server settings, i get

Could not download configuration file: 407 — Proxy Authentication Required ( Forefront TMG requires authorization to fulfill the request. Access to the Web Proxy filter is denied. )

Do i need to setup any proxy settings anywhere else? Any other hint?
