Wordpress All In One SEO plugin not sharing to Facebook wall

Question

I use to implement Facebook's OpenGRaph protocol on my pages (WordPress) based on the All In One SEO plugin.

With each page:

<meta property="og:type" content="article">
<meta property="og:title" content="my_title">
<meta property="og:url" content="http://my_site.jp">
<meta property="og:description" content="my_content">
<meta property="article:published_time" content="my_published_time">
<meta property="article:modified_time" content="my_modified_time">
<meta property="og:site_name" content="my_site_name">
<meta property="og:image" content="http://my_site.jp/wp-content/uploads/2017/05/my_image.png">
<meta property="og:image:width" content="600">
<meta property="og:image:height" content="315">
<meta property="og:locale" content="my_cocale">

But i get these error when checking with Facebook developer debug:

URL returned a bad HTTP response code.
Inferred Property
The 'og:image' property should be explicitly provided, even if a value can be inferred from other tags.

But I don't have any solution. Have your solution for this problem?
