    The error still shows up.

    I reset the encryption on three hosts for testing and rebooted them. After 30 minutes the connection fails on all three hosts with the error seen above.

        I rechecked the error and it was a little bit different then before. Sorry!

            @Tom-Elliott

            Sporadically for the next 4 hours.

            I checked the DB table hosts and noticed that the column hostPubKey emptys every 30 minutes after the host checked in.
            So for 30 minutes the hosts are fine and then the connection breaks.

              @mp12 that’s kind of intended. The idea to to reset the key so as to prevent hijacking. I can fix fairly quickly, kind of. That’s why ask ask for availability

                I’ve pushed up to the working 23 branch what I hope will fix this.

                invalid host or not, the client wants to see the rest of the services (which none were sent).

                IHC (Invalid Host Certificate) wasn’t coded to be json received, so the trick is trying to figure out when to send all the data vs. just the error. In our case here (the {"error":"ihc"} you saw) the client (as far as I can tell) is actually requiring it to be seen as #!ihc rather than a json string. I’ve pushed code to ensure that ihc will be thrown properly, as well as passed the data for the client in the other case (invalid host) – though I know this isn’t your issue.

                  Confirmed changes in RC-23 branch are working as intended now.

                    I seem to have this issue with RC22. Just to confirm upgrading to RC23 will resolve the issue.
