      So i tried Demo Proxy (should rename that to Demo Gateway)

      I tried with a combination of

      • @noproxy, @tunnel
      • @noproxy, @proxy
      • @noproxy, @proxy-tcp

      Interestingly enough i didn’t get anything in the monocle gateway logs

      I read a note somewhere that said the demo stream only works with proxy-tcp and not proxy or tunnel tags

      for all 3 Alexa attempts to load the stream and then says “Sorry, Something Went Wrong”

        OK, take a look in your Camera Feed History and lets make sure that the Alexa InitializeCameraStreams response is pointing directly to your gateway DNS hostname and not our redirection server. Just post the response here and I’'l review it.

        Thanks, Robert

          Again thank you so much for working with me on this. I am willing to do whatever it takes to make this work…

          I tried those tags with my legit cameras (Foscam and Amcrest) with (@noproxy, @tunnel )

          I get “Sorry, Something Went Wrong”

            No problem, let just stick with @noproxy, @tunnel tags on “Demo Proxy” for the time being. Even if it does not result in the demo camera working, it keeps things simpler for now – the first goal is just to see TCP connections from the tablet in the Monocle Gateway log after an Initialize Camera stream.

            Thanks, Robert

                },
                {
              

              I did 3 attempts with the @noproxy as listed above, all 3 show that it is indeed using the direct URL instead of the redirect URL.

              Okay, i hear you about the @tunnel, @noproxy… i will leave it like that from now on

                Here is the WebUI log

                [

                  },
                

                This time she said “Im not sure what went wrong”

                    OK, so looking more in-depth, I was wrong, the tag @noproxy should not be included. It looks like when using the @tunnel or @proxy (or @proxy-tcp) tags we skip that redirection step anyways.

                    So just include @tunnel only and then what I would expect is additional lines in the gateway log like this example:

                        So it’s certainly acting like the tablet is not able to establish the RTSP connection to the gateway.

                        I know we have already checked the DNS, SSL cert, IP address, access to port 443, etc. So I think we know that a connection is not getting blocked by the typical actors.

                        Amazon does not provide us any details on how to further diagnose Alexa camera connection related issues on the Alexa hardware side. It’s just a black box to us.

                        I think some network packet sniffing might be in order to try and determine if the Alexa device is trying to connect to the gateway. This seems to be where we are stuck once again. Tracing outbound requests from the tablet device should reveal TCP attempts on port 443 to the gateway.

                          Sure i can try to set something up with some guidance, i have used them in the past but i might need a little direction on setting it up. I mainly have windows on the network but may be able to setup something on one of the Raspberry PI3 i have.

                          Also the lenovo show is an android OS so im not sure if there is an android packet sniffer that can be installed directly on it. It isn’t rooted which may be necessary. I will do a little research unless you have some specific guidance.

                          Question: do you think its worth replacing my firewall. I have an older netgear that i have used in the past that i can try swapping out the USG with.

                            You might look into the USG and see if it supports any packet sniffing capabilities. I use a PFSense router and it does have support for traffic sniffing (with additional packages installed).

                            It’s hard to say if swapping out the router would make any difference … we really don’t know where the problem lies just yet.

                            Thanks, Robert

                              Im haven’t had a chance to analyze it yet, but essentially i installed a android packet capture on the Lenovo Smart Tab, started a packet capture and asked Alexa to show Demo Proxy

                                Apology for the large messy file. Using tcpdump command SSH’d into the USG and putty logging

                                  @skarragallagher said in Foscam R2 with Lenovo Smart Tab:

                                  I did not see any packets either in the “Source” or “Destination” with the IP address of the gateway: “192.168.1.26”. In fact the only local addresses found are “192.168.1.1” and “192.168.1.155”.

                                    I did not see address “192.168.1.26” in the TCPDUMP file either.

                                      Let me see if can get a better packet capture, helps to know what you are looking for.

                                        Well i did some extensive testing last night. I plugged in an ethernet adapter and moved the gateway to my laptop so they could share the same switch. I ran wireshark and tried to reproduce the issue. I never saw any communication with the Lenovo Smart Tab to the gateway. I started checking the basics again and I did identify a type in the static record i set for the FQDN although correcting this didn’t fix the issue.

                                        I basically reverting everything to the way it was able to resolve the address, ping the gateway with the FQDN, do a TCP Ping on port 443, and do an SSL probe using the Ping & Net app on the Lenovo Smart Tab.

                                        In the gateway i did see a socket connection attempt like in your example. Of course not from Alexa or when trying to show the camera, but when i did the SSL probe test. So i know there are no internal networking / connectivity issues that is blocking the attempt

                                        The packet capture that i did on the Lenovo Smart Tab using the app is kind of hard to read because it uses a VPN connection to capture using the man in the middle exploit so thats where all the 10.x.x.x. addresses are comming from there.

                                        For some context:
                                        192.168.1.155 is Lenovo Tab over WIFI
                                        192.168.1.199 is Lenovo Tab over ethernet
                                        192.168.1.105 is my laptop that i was doing testing from
                                        192.168.1.26 is obviously the gateway and home automation server

                                        Here is a more specific tcpdump that i ran on the USG. I recreated the error twice, once targeting the Lenovo Smart Tab over ethernet (192.168.1.199) and once targeting the the gateway. I am thinking though that this won’t capture internal communication i.e. Lenovo Smart Tab <–> Monocle Gateway but only when it traverses the internet.

                                        This is why i tried moving both the Lenovo Tab over ethernet and the Gateway to the same switch that the laptop is wired to and running captures. This did effectively capture my ping requests from the Lenovo Tab, to the gateway (running on the laptop) but however that was the only communication between the two devices. Its as if Alexa isn’t getting the URL at all and or not even attempting to connect.

                                        Here is the wireshark packet capture

                                          Just for confirmation that we are able to properly capture the packet attempts, please try to view the Demo Direct camera feed and then see if IP address “54.82.183.87” is captured as a destination from the tablet.

                                          I agree with your testing method/approach and points on not being able to capture intra-LAN packets from the tablet to the gateway that may not cross the USG router.

                                          Thanks, Robert

                                            Yeah let me work through that, when i attempt the packet capture on the Lenovo via the app installed it won’t connect to Demo Direct over the VPN connection it creates to actually capture the packets. I will try some other apps and potentially investigate rooted this device.

                                            In the mean time i will use the USG tcpdump method to attempt to capture this traffic and verify this connection is captured
