I'm having an issue with browser playback.  I've tried multiple computers and Firefox, IE and Edge with the same results.  The movie will play for a few minutes and then freeze.  The only way to resume playback is to close the tab, open a new one and then it will start playing again.  Anywhere from 60s to 5 minutes later, it happens again.   Emby is running inside of a docker.   I keep seeing this in the log file:   2020-04-04 11:14:44.158 Info HttpServer: HTTP Response 204 to 192.168.0.13
