Hi @jess!
I did have the wrong cert setup: it was the one I was using for apache. I can’t re-use the same cert for nginx, since it does require cert -> intermediate -> ca. I grabbed the pem version of it that I had made for monit and tried that instead. Accessing via curl now returns a 404 error (previously without intermediate -> ca it showed a cert error).
The error in the nginx logs does persist when I try to play a video. Is there possibly something wrong with my Access-Control-Allow-Origin part of the header response (the browser error)? I did check the hls section in kaltura.conf for nginx and it seems to have the directive to add it, but perhaps it needs to go somewhere else.
