varnish serve old object during refresh

[AD]

The VCL looks right at first glance.  Are you sure the object is actually
being cached in the first place?  You can confirm with something like this
in your vcl_deliver

if (obj.hits > 0) {
     set resp.http.X-Cache = "HIT";
     } else {
     set resp.http.X-Cache = "MISS";
  }
