The problem with cert for Plex is that they have a lot more clients and these all handle things/security differently which is part of the reason the "security fixes" have been long coming to Plex. With Emby is easy for now as they only have a couple of clients to worry about.
That is a hole Plex keeps making deeper and deeper, and I am wondering if they still can get out of it....
Thanks, seems to be working, but I'm no expert cryptographer, I'll have to fiddle around with the certs in a bit to make sure there's nothing blatantly bad, but it seems good enough from here (Seems like Plex has a sub-CA cert which signs *.${RANDOM}.plex.direct, your device then jumps on ${IP/./-}.${RANDOM}.plex.direct).
Just wanted to say thanks for the excellent and innovative work here. I am sure you will get fewer kudos than you deserve for such a cool hack, most of us greatly underestimated the complexity of this rollout. Good work! :)
