It works like a charm on any mobile, but not on Windows Phones with Internet Explorer.
check that link in any Internet Explorer, tell me please why I cant see?
It doesn’t work also in email when you look with Microsoft Outlook. If an email contain an image from a web site with your FREE SSL, It does not show the image.
If you look at the same email with chrome and gmail etc, you can see the images from the web site.
Could you guide me, what must I do? Or you can do a little chage for all platforms?
Fix your server configuration; this has nothing to do with the cert. See:
Your site doesn't work with IE11 on any platform other than Windows 10, or with old versions of Safari. But again, this has nothing at all to do with the cert.
