You were very close. I am posting my answer for those who are searching and stumble upon this post. You will need to be using Apache2 >= 2.4.17 to use this and several enabled mods (proxy, ssl, proxy_wstunnel, http, dir, defalte, env, headers, proxy_balancer, proxy_http, rewrite I think are all of them):
Edit August 2019
Added some new information and now the below configuration enables you to watch trailers and hear TV Show theme music.
Edit February 2021
- Updated Content Security Policy
- Added Permissions Policy
- Removed Rewrite
- Added
<Location> sections
- gzip defalte for common files (javascript, xml, etc.)
- Updated Ciphers
With SSL (new February 2021)

### Content Security Policy for the overly paranoid - may break with Plex server updates (works with server version 1.21.3.4046 and 1.21.3.4021) ###
Header always set Content-Security-Policy "default-src 'none'; base-uri 'self' ${serv_name}; font-src 'self' data: ${serv_name}; media-src 'self' data: blob: ${serv_name} https://*.plex.direct:32400 https://video.internetvideoarchive.net https://*.cloudfront.net; script-src 'self' 'unsafe-inline' 'unsafe-eval' domain.com ${serv_name}; style-src 'self' 'unsafe-inline' ${serv_name}; img-src 'self' data: blob: https: ${serv_name}; worker-src * blob:; frame-src 'self'; connect-src 'self' https: domain.com ${serv_name} wss://*.plex.direct:32400 wss://pubsub.plex.tv; object-src 'self' ${serv_name}; frame-ancestors 'self' domain.com ${serv_name}; form-action 'self' ${serv_name}; manifest-src 'self' ${serv_name}; script-src-elem 'self' 'unsafe-inline' domain.com ${serv_name} www.gstatic.com"
