go get tls handshake timeouts

[Rich]

When I run 'go get github.com/user/packge' I get a TLS Handshake :

go: module github.com/user/package: Get "https://proxy.golang.org/github.com/user/package/@v/list": net/http: TLS handshake timeout

So I set GOPROXY=direct

Now I get

go: downloading github.com/user/package v0.5.0
go: github.com/user/pac...@v0.5.0: verifying module: github.com/user/pac...@v0.5.0: Get "https://sum.golang.org/lookup/github.com/user/pac...@v0.5.0": net/http: TLS handshake timeout                                                                                                                                                                                
 I know I didn't put a real package in -- because it happens with every package.  This also only happens when I am connected to my company VPN -- Company also uses proxies to get out. I would have better luck getting a river to flow uphill than for them to change their vpn or proxy policies. This used to work, until I had to reinstall my mac.

I also can set different proxies to get around most of their corporate bs. Setting those proxies works for cloning a github repository, I can curl, wget -- it all seems to work just fine. I just cant run 'go get'

Adding the company root CA and intermediate CA using certmgr.msc was enough for this issue to go away.
