Azure blob storage images cause security issues when sharing webpages in Facebook

Question

All website images are stored in the Azure blob storage with standard urls like:

https://****.blob.core.windows.net/*.jpg

Each page has "og:image" with link to the image stored in the blob.

When I am trying to share some web page I see a security issue (or similar messages with asking to enter captcha because of unsecured content):

I can't find any official references by Microsoft or Facebook how to fix this issue or whitelist the domain.

I get same security issue warning when I try to post your image on Facebook. If you ensure the included images are safe and Facebook made mistake, you could click [let us know] to report it.

<meta property="og:image"              content="https://donorua.blob.core.windows.net/public-images/df1f3ede-6502-46fc-8c52-10317d8e5a6e.jpg" />

Besides, I save your image in my Blob container, and then post the image, I find the imgae could be posted. So if possible, please try to move the images to another container or rename the images in your Azure Blob container.
