Caddy: v2: Http_ntlm option resulting in runtime error

[signalcodec]

1. My Caddy version (caddy version):
   20200304.7

2. How I run Caddy:
   a. System environment:
   Debian as an LXC container under Proxmox, also tested with a VM under proxmox

d. My complete Caddyfile or JSON config:

starrsfamily.com {

reverse_proxy 10.99.99.181:443 {

header_up Host {http.reverse_proxy.upstream.hostport}

transport http_ntlm {
tls_insecure_skip_verify
}

}

}

1. The problem I’m having:
   Caddy is failing to start, it throws an error message

2. Error messages and/or full log output:

I believe I've fixed it in PR #3120. Can you test with one of the pre-built binaries from Azure?
