Facebook share button, use og:image with non-default HTTP port

I have a web page with og:image meta tag

<meta property="og:image" content="http://server:9210/image.jpg"/>

When I use facebook debugger http://ift.tt/1sbmVox it gives warning that is it unable to download the image. The url is correct and accessible from the internet (host is changed here).

"These are the raw tags that we found" section shows that the facebook has found the og:image tag but the port is replaced with default 80:

<meta property="og:image" content="http://server:80/image.jpg" />

Does facebook support non-standard ports in og:image tag?
