NGINX stripping websocket "Upgrade" headers

[J.R.]

> Got it figured out, this is a quirk of HTTP/2.0 vs 1.1. Per RFC-2616:

I tried to follow all your comments on reddit & plex, but I'm not
really sure if you resolved this issue or just decided it was
impossible...

Have you tried using the nginx stream module?

http://nginx.org/en/docs/stream/ngx_stream_core_module.html

As for your issue about needing to include both the LE cert and your
own in one file... Most people figure that out when they enable OCSP
stapling... hehe... But yeah, I was scratching my head too for a bit
at first then I found some posts mentioning what to do...
