Embedding Stopped Working in June

This SSL matter is a problem for me, because IIS 7.5 only supports one certificate. I’ve got that for my commercial site. But if I try to add certs to the other sites, there is a contention/conflict.
Very unfortunate because Twitch was a good quality streaming platform which worked right from OBS without having to set up a stream first on a browser as is the case with Youtube and Facebook and Twitch doesn’t ban me if a bit of copyrighted material is shown during a presentation/demonstration.
The last time the embedding broke on me was about a year ago, when it was necessary to make changes to the embedded code to make it work again. I normally leave things alone unless something stops working.
