Errors When trying to install Monocle-Gateway.exe

Monocle

Yes, if installed as a service, it can run in the background as a NT System Service. Basically it’s just running the same EXE in the background under a service account and started automatically when the machine reboots.

It easier to test with when just running the standalone EXE, but once its all working for your system, you would probably prefer it run as a service.

Thanks, Robert

@spicymikey It is not a Win server. It is desktop running win 10 Pro. I will try to find what ever is on 443. You keep saying I am running .exe, is there another way to do it? Also, I am trying to get this to work on Fire HD 8 inch 8th gen with latest O S. Thanks for help.

Yes Monocle makes several executables for various platforms. I was just referring to the fact that it seemed you were doing this on Windows when you mentioned “Task Manager” and “exe” files.

Did you find what was using 443? If not, if you have another pc to use, try that. But it should not be hard to find what has a hold on 443. Take a screenshot of all the programs in your “Program List” and share it here. I bet we can spot the likely culprit.

Yes It showed to be Chrome. Stopped service and install worked with no errors. I don’t know if I should have but I added the TAG @tunnel to the setup of the cameras. Monocle then showed a popup where it added the cameras. I removed the devices from Alexa and added back after the change. The kicker is that Alexa Echo Spot and Fire HD 8 inch 8th gen in show mode, neither will show the cameras.

Chrome! ?? What? Chrome should not be listening on port 443? Maybe you have some extension installed that is doing this?
Glad that solved it though.

I don’t know if I should have but I added the TAG @tunnel to the setup of the cameras. Monocle then showed a popup where it added the cameras.

Yes, @tunnel by default, but it may depend on your specific cameras. Which cameras are you trying to get working? (make/model) Some cameras may require @proxy or @proxy-tcp instead of @tunnel.

I removed the devices from Alexa and added back after the change.

That’s fine, but for future reference, you don’t have to do this step in the future for tag changes.

The kicker is that Alexa Echo Spot and Fire HD 8 inch 8th gen in show mode, neither will show the cameras.

Were they working at any point in the past? I know the spot is limited to showing streams of 1080P and lower resolutions, so if you camera is configured to stream a higher resolution, the Spot won’t display it. You would have to change the settings on the camera itself (not in Monocle).

You might need to post the contents of the Monocle Gateway log to better see what’s going on.

Thanks, Robert

Yes it worked several months ago on the Spot. I just bought the tablet. I am trying Hikvision Microseven and some noname ip cameras. This time I do not see Monocle running as a service?

pedenfield

I have checked the URL’s that I am using and I am able to pull up a stream using VLC on all of them.

Monocle

@pedenfield

OK, the startup looks good in the log.
Capture the log while asking “Alexa, show me the XXX camera” and let’s see what happens.

Thanks, Robert

@pedenfield

OK, so immediately after the “INITIALIZE RTSP” section, you should see incoming TCP requests from the Alexa devices. In this log they are missing, which means the Alexa devices are not able to connect/communicate with the Monocle Gateway.

1.) Are the Alexa devices on the same network as the Monocle Gateway. (not on a separate VLAN or on a Guest Wifi, etc)
2.) Check (or disable) the Windows Firewall to make sure it’s allowing port 443 to be used by Monocle Gateway.
3.) What type of router are you using? Some routers will block DNS resolution of public DNS hostnames that resolve to internal/private IP addresses. (See DNS REBINDING)
4.) Is the auto-detected IP address of 192.168.0.110 correct for the Monocle Gateway. The Alexa device will use this to connect.

Thanks, Robert

pedenfield

Same network.
2, Disabled my Trend Micro firewall
Router is a TP-Link Wireless Router Touch-P5
Yes. That is the Pc Monocle is installed on.

@pedenfield

Are you using PiHole or any other DNS server on your network?

Thanks, Robert

pedenfield

No. I am using NoIP because I can’t get static IP.

Monocle

@pedenfield

In the startup of the log file look for the “FQDN” entry. This is the unique hostname that is assigned to your gateway instance and registered as a publicly resolvable DNS entry.
Open a command prompt on your Windows machine and enter the following command:

nslookup xxx.mproxy.io

(where xxx.mproxy.io is your FQDN.)

It should return a result with your gateway’s local IP address. 192.168.0.110

If you don’t get this IP address, then something is blocking the DNS resolution of that domain name. Most likely your router or DNS server is blocking resolutions to local IP addresses (DNS REBIND).

Make sure to try this nslookup test on the gateway machine as well as another computer on the same network if possible. Basically we are trying to make sure that the Alexa devices on the network would also be able to resolve this hostname by simulating the DNS resolution from another device attached to the network.

Let’s start with this test and see what happens.

Thanks, Robert

pedenfield

I think I have the FQDN number right.

@pedenfield

So this confirms that DNS is the issue.

Here is what I get when attempting the same test:

$ nslookup 2b49b758-a6fd-4a36-a6ac-29b674ff1ce5.mproxy.io
Server:		172.20.10.1
Address:	172.20.10.1#53

Non-authoritative answer:
Name:	2b49b758-a6fd-4a36-a6ac-29b674ff1ce5.mproxy.io
Address: 192.168.0.110

So you see, I’m getting the actual resolved address of 192.168.0.110 which is correct.

You can also try the same command using Google DNS server at 8.8.8.8:

$ nslookup 2b49b758-a6fd-4a36-a6ac-29b674ff1ce5.mproxy.io 8.8.8.8
Server:		8.8.8.8
Address:	8.8.8.8#53

Non-authoritative answer:
Name:	2b49b758-a6fd-4a36-a6ac-29b674ff1ce5.mproxy.io
Address: 192.168.0.110

So the issue is most likely your router which I assume is at address 192.168.0.1 based on your previous attempts.
The router is probably blocking resolution of the DNS hostname to a local IP address.
You will need to lookup instructions for how to allow a specific hostname (2b49b758-a6fd-4a36-a6ac-29b674ff1ce5.mproxy.io) to be allowed and not blocked.

Thanks, Robert

Thanks. I will do some checking and let you know what I find. You have been most helpful…

@pedenfield

When trying to research this for your router, the keyword “DNS REBIND” or “DNS REBINDING” is what this behavior is typically called. It’s a security measure that some routers implement.

Using Google it the lookup works
