      Can you all please try again now and see if the issue is resolved? You may need to restart your Monocle Gateway instances.
      We did find a server-side error that potentially could have caused this but it did not impact all users … or at least not all at the same time.

      Thanks, Robert

            I am getting the ‘Invalid WebSocket frame: RSV1 must be clear’ error. I have already tried uninstalling and reinstalling. I have stopped and restarted Monocle, but there has been no change

                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…

                                    parece não ter resolvido!!
                                    It doesn’t seem to have resolved, I still have the same problem…

                                        @jeffhouchin On Ubuntu, was working fine for a few months and now RSV1 must be clear error. Tried installing on Windows and got the same error.

                                          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.
