Port already in use?
-
Hello,
I’m trying to set up Monocle Gateway, but Alexa can’t show my cameras.
I think the port 443 is already in use on my machine by node-red.
How to solve the issue?

You can check to see what processes are already using port 443 using the following command:
(ref: https://www.cyberciti.biz/faq/unix-linux-check-if-port-is-in-use-command/)$ sudo lsof -i -P -n | grep LISTEN uv4l 334 root 4u IPv4 13349 0t0 TCP *:8080 (LISTEN) sshd 463 root 3u IPv4 11156 0t0 TCP *:22 (LISTEN) sshd 463 root 4u IPv6 11158 0t0 TCP *:22 (LISTEN) monocle-g 759 monocle 13u IPv4 489943 0t0 TCP *:8555 (LISTEN) monocle-g 759 monocle 15u IPv4 489944 0t0 TCP *:443 (LISTEN) monocle-p 774 monocle 3u IPv4 495953 0t0 TCP *:8554 (LISTEN)
If something else is already using port 443, you will need to change that application to use an alternate port.
Monocle Gateway requires port 443 because Alexa device will only connect to stream on port 443. (and we need Alexa to connect to the gateway.)
Other options would be to move the gateway to another server. Add an additional IP interface (or simply assign a secondary IP) so that Monocle get’s its own dedicated network/IP to listen on and the other app can remain on the existing. Docker containers, Virtual servers, etc. All these options of course require a little more advanced setup and networking knowledge to make sure you get it all configured correctly.
Let us know how it goes and which path you are going to try.
Thanks, Robert

Hey Robert,
thanks for your reply. In fact, another service was active at 443. I stopped it and the error message above does not come anymore. Unfortunately, Alexa still can not see my camera. I do not know where to look, why the camera does not work.I would like to move the gateway to a Docker container, which gets its own IP address on my server. Is there somewhere a guide? I think that will also interest many other people.
Thanks! :)

For Docker images of Monocle Gateway, please see:
- https://monoclecam.com/monocle-gateway/install/docker
- https://hub.docker.com/r/monoclecam/monocle-gateway
These are based on Alpine images. Pay close attention to the networking notes, the networking mode is very important for the Monocle Gateway.
Honestly, I would try to get it working first before going the Docker route. Once you have your cameras at least working, then you can move it into a Docker container.
Any log data from the now listening Monocle Gateway as you ask Alexa for a camera stream?
Thanks, Robert

This is the tail, when I ask my Echo Show 5 for the camera:

These are my settings in the gateway:
I use Zoneminder on my network to stream my cameras. With the settings here, the image works fine in Zoneminder and VLC. What am I doing wrong?
Thanks!

Are you using a Fritzbox on your network?
If so, search the forums for “Fritzbox” and/or “DNS Rebinding” these routers must have some additional configuration to permit the DNS hostname resolution for the Monocle Gateway.If you log, I can see that the camera’s are tagged correctly and we are getting the request from Alexa and notifying your Monocle Gateway instance. What’s missing is the Alexa device making a TCP connection to the gateway to start the stream.
Thanks, Robert
