In order to connect the internet, from my office network; I had set proxy address and port inside Manage Jenkins -> Manage Plugins -> Advanced -> Proxy settings.
It used to build fine there.

At my home network on the same laptop, I have to remove these Advanced proxy configurations for me to connect internet. Even though I do ths, and restart tomcat and jenkins; whenever I build the project; it's trying to use the same old proxy server !!! And fails.
I then rechecked, Advanced Tab, the proxy is not configured. But I don't see why it is trying to use the proxy settings here

Any idea where I am failing here ???
