very strange

I am working for 5 days now to get my problem solved.
I added all og:tags in your plugin but Facebook is OR ignoring it or I am still doing something wrong.

Try to share/scrape http://www.theatervacatures.com website or one of its posts.

This is part of the source code:

<!– wpsso meta tags end –>’

1. Everything seems right.
But still I am getting an facebook error in the debugger.
Error 503 (something to do with the og:mg tag not excisting. It is there in the source code???

2. also the scraper return another error while scraping:

‘<!DOCTYPE html PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN” “http://www.w3.org/TR/REC-html40/loose.dtd”&gt;
<html>
<head><meta http-equiv=”content-type” content=”text/html; charset=utf-8″></head>
<body><p>AsyncSocketException: connect timed out, type = Timed out</p></body>
</html>’

Please help, what am I doing wrong?
