How to config local proxy for WP?

Hello Clay

Iam having trouble bringing up the site when I am behind a proxy. I tried Open Site SSH and it gave me error

Tunnel or SSL Forbidden logout (on VPN)
proxyconnect tcp: dial tcp: lookup proxy.proxysherwin.com: no such host (Home Network)

At work if I turn off wifi the site works.
At home I don’t need to turn off wifi to make it work.

Iam trying to understand what is the setting i need to have if I content from youtube hosted on my site.

Thank You
Aruna
