Once again I find myself in need of your collective genius. I have a website built in ASP.NET 4.5 using c#, its a web forms site if that is at all relevant. I have the following script in my master page to generate the required meta og:whatever tags.
var ogtitle = "<meta name=\"og:title\" content=\"" + this.Page.Title + "\" />";
var ogsname = "<meta name=\"og:site_name\" content=\"Griffiths Web Design\" />";
var ogtype = "<meta name=\"og:type\" content=\"website\" />";
var ogdesc = "<meta name=\"og:description\" content=\"" + this.Page.MetaDescription + "\" />";
var ogurl = "<meta name=\"og:url\" content=\"" + HttpContext.Current.Request.Url.AbsolutePath + "\" />";
var ogimg = "<meta name=\"og:image\" content=\"www.griffithswebdesign.com/images/binaryearth.jpg\" />";
fbmets.Text = ogimg + ogtitle + ogurl + ogsname + ogtype + ogdesc;
Which, when I run the site generates the following meta tags (I know they are there because I can see them when I view source)
<meta name="og:image" content="www.griffithswebdesign.com/images/binaryearth.jpg" /><meta name="og:title" content="A Simple blogging system in ASP.NET" /><meta name="og:url" content="/Blog/Post/24" /><meta name="og:site_name" content="Griffiths Web Design" /><meta name="og:type" content="website" /><meta name="og:description" content="A Simple blogging system in ASP.NET" />
Despite this when I try to share a link from my site to Facebook it comes up as not found. When I use the facebook debugger it is unable to find the tags. Is there something I'm missing? or have I completely misunderstood the process? as far as I can tell I have the required tags present in each page thanks to the script in the master page. Obviously something is wrong but as I said I'm lost.
Although this appears to be happening on every page here is a link to a page so you can have a look:

Any help would be greatly appreciated :)
Your website does not work with ipv6, although it has a AAAA record. This is my request when I use ipv6:

When I force ipv4 using wget (wget -4 -S http://www.griffithswebdesign.com/Blog/Post/24), I see this:
