Bing Webmaster Tools : Site Thumbnail Image?

[deepee_oz]

Hi All

When I log into my Bing Webmaster Tools account it takes me to the "My Sites" page.

All sites except one have an icon in the left column that is a thumbnail representation of that site's homepage.

However, one site thumbnail shows as a gey box with an image of what looks like chain links in the middle:-
[dropbox.com...]

Anyone have any thoughts as to what that means?

Thanks

Solved it myself so sharing the info.
I had recently put that site on Cloudflare. As soon as I disabled Cloudflare, the normal site thumbnail appeared.
Bing also had problems indexing my https site map while using Cloudflare.
It indexed properly again once Cloudflare was disabled.
