Our twitter cards were working fine until a couple days ago, now they appear blank.
Upon inspecting the console it seems that twitter is calling our twitter:player via a HTTP , which of then is denied since twitter is HTTPS (see image)
The odd thing is that our site doesn’t ever call this over HTTP, if you look at the source code its HTTPS (see image below)
How do we fix this? Is twitter trying to load the player over HTTP since the link is HTTP? I tried loading that link over HTTPS in the validator but it resulted in a SSL handshake error.
