Description

    location ^~ /xxx {
        resolver 8.8.8.8 ipv6=off;

        proxy_set_header   Host www.mydomain.com;
        proxy_pass https://www.mydomain.com;
    }

Even with ipv6=off, error log reports failure to connect to IPv6 address.

2015/02/19 05:16:06 [error] 30169#0: *69 connect() to [2001:4860:400b:c01::79]:443 failed (101: Network is unreachable) while connecting to upstream, client: xxx, server: www.moov.cc, request: "GET /xxx HTTP/1.1", upstream: "https://[2001:4860:400b:c01::79]:443/xxx", host: "xxx"

It works if I change https to http.

Internal resolver is only used for proxy_pass with variables.

More specifically, in your case (i.e., without variables)
it is resolved only once on start up with the system resolver.
