      I’m trying to get to the bottom of this issue but its difficult when I’m unable to reproduce it locally.
      I have made some additional changes on the server side. Let’s see if that helps the problem.

      Please post back here if you continue to get “Invalid WebSocket frame: RSV1 must be clear” errors.

      Thanks, Robert

              Same here. Restarted the gateway and rebooted the server several times. (Linux casemedia 5.4.0-1032-raspi #35-Ubuntu SMP PREEMPT Fri Mar 19 20:52:40 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux)

              Double checked nothing else is listening on 443 (this is not that problem).

                I have reverted to restoring a backup of the previously “known” working server to see if this gets rid of the ‘Invalid WebSocket frame: RSV1 must be clear error. Please let me know if you continue to get this error. It seems like all this started happening after a recent server upgrade so I have reverted back just to see if the problem goes away.

                Thanks, Robert

                    Splendid. Working again for me too, gateway starts cleanly.
                    Thank you.

                        @ecanivan said in Invalid WebSocket frame: RSV1 must be clear:

                        Gateway was working for a couple of days and then just stopped with this error. I don’t ever see the MONOCLE RTSP SERVICE - INITIALIZED message so I’m assuming it is during that process.

                        Estou ainda com esse problema tanto no linux quanto no windows…

                          It doesn’t seem to have resolved, I still have the same problem…

                                OK, I’m looking further into this issue. I have made some changes on the server, please let me know by posting here if the latest changes resolve the issue of if its still a problem. I have never been able to reproduce the issue so its somewhat difficult to nail down.
