Foscam R2 with Lenovo Smart Tab [SOLVED]

skarragallagher

Here is my Demo Direct Feed, Can you validate that i have this configured correctly. Note the port change and tag, everything else should be the same

This one going through the proxy with @proxy-tcp tag shows this:

@skarragallagher

Can you revert back to the URL rtsp://demo.mproxy.io:443/test and test again both with and without the @noproxy tag. I’m just trying to isolate the issue and make sure we are working on the exact breakdown.

If it’s absolutely working with tag @noproxy and definitely not working with no tags, then that points to a new issue we have never seen before. But it’s a clue and possibly we can move to the next diagnostics step once this is confirmed.

Thanks, Robert

Monocle

@skarragallagher

After confirming the steps above in my last post, you can move forward and try RTSP URL: rtsp://demo.mproxy.io:554/test and include both of the following tags: @noproxy, @tunnel and lets see if anything new shows up in the gateway log.

If the key to getting this working is the tag @noproxy, then I suspect I know what the issue is. Tag @noproxy tells our servers NOT to use a RTSP REDIRECT. In fact, I should change it to @noredirect to avoid confusion because the word “proxy” in this case means something different than the @proxy used with the gateway. This issue has never come up before and we have never shared this tag for use until now. By default we use a RTSP redirection stage as this was the original working implementation method before Amazon started implementing stricter and stricter access policies.

Thanks, Robert

skarragallagher

Yes, i have 2 demo cameras in my configuration

The Direct one that isn’t using the gateway is the first camera that i have gotten to work at all. I am 100% positive that it is working using the @noproxy and as soon as i remove that it stops working

skarragallagher

I will configure Demo Proxy with @noproxy, @tunnel and see what happens

skarragallagher

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”

Monocle

@skarragallagher

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

skarragallagher

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”

Monocle

@skarragallagher

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

skarragallagher

Here it is with

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

skarragallagher

Note that it did not show the initial Loading Demo Proxy screen that i am used to seeing

Monocle

@skarragallagher

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:

Alexa shows Camera Loading Screen and then about 10 seconds later it says “Camera Doesn’t Support That”

Monocle

@skarragallagher

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.

skarragallagher

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.

Monocle

@skarragallagher

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

skarragallagher

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

See if this link works for you. File is 1.2mb

skarragallagher

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”.
