Streaming server not working directly

[alanmilinovic]

I tried to configure the server to work behind proxy to expose it outside with SSL and certificate, and when I tired to play some video it is saying (error 500):
{"error":{"code":10,"message":"Failed to read hls playlist: Probe process exited with code: 1"}}

When I click on "Open in external player" it downloads the playlist and it is working fine.

Same video is playing fine with http protocol.

Any idea?
