Unable to get a video or a clip to embed at all

I copy the iframe code from the share/embed button on the actual page of the clip I want.

I paste it to my wordpress page.

I change the example url to the url of my website.

And then… it says this clip is no longer available.
Which, you know, kinda doesn’t work since I am watching the clip on twitch to get the code. Plus I have tried it with a clip I made only an hour ago.

Link to page with broken embed please

Here is the page I was attempting to work out yesterday.

The problem is your website is not avalable over SSL.

SSL is required for Twitch Embeds.
