I no longer use Apache as a reverse proxy and moved to NGINX. No further updates will be made to this configuration. It may or may not work in the future, no warranty or support will be provided.
This VirtualHost configuration has been tested with the minimum requirements of Plex Media Server Version 1.16.5.1488 and Web Version: 3.108.2.
The TLS configuration only allows clients that support TLS 1.2+, this may cause issues for legacy clients. You may need to adjust this if specific clients have issues connecting. If however you are OK with having just TLS 1.2+ support, you can also enable the "Disable weak TLS versions" setting on your Plex server, given the reverse proxy will prevent a successful TLS negotiation for such clients anyway.
