        I reset the encryption data at 15:29 and now it is 16:00.

        In the hosts column hostSecTime the entry shows 2016-11-09 15:59:31
        No idea if this has anything to do with it.

          I believe I found the issue. I fixed it and realized the “fix” was not proper, but was more appropriately handled a bit different (missing one component). I’m only going to guess here, but this host is not already registered?

          I’ve tried in the working-RC-22 to make sure the requestClientInfo call returns the data as appropriate now.

          Essentially what was happening (I think) is the host is not valid/registered/found in the system. There should’ve been a return of the data immediately in json form, which you can see the change was doing, but the return goes to a function that is more or less specific to the direct service calls.

          However, the return needs to be echoed if another element is throwing an immediate error.
          You can see this here:

              The host(s) were registered before. Will check if RC-22 fixes this error.

                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.

                        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.
