Crowsnest: reachable trough browser but not working in mainsail

[stable sphinx]

Hey!

As the title already says im trying to use a Logitech C270 with Mainsail trough crowsnest. I can reach it using this url 192.168.178.191:1335/webcam/?action=stream which is my local ip, combined with the port im running mainsail on and the camera works like expected ( see picture ). Problem is that if I enter the same stuff like above into the Mainsail webcam settings it just displays a blank white-ish image ( see picture ). I already tried restarting the crowsnest, klipper and Mainsail but that does not change anything. Yesterday when I got the camera everything was just a matter of plugging it in and editing the config. Below ill attach some logs and configs

Please explain why you use port 1335?

[stable sphinx]

I have lots of stuff running on that machine so all those ports like 8080, 443, 80 are already occupied

[cobalt heath]

Then you need a special setup because Ports 8080-8083 are covered by mainsails nginx configuration.

/webcam/ is a nginx reverse proxy url

[stable sphinx]

But why did it work yesterday? I just unplugged the cam and replugged it today and not everything is broken

[cobalt heath]

Its easy, if you have another application running on prt 8080 and ustreamer trys to start with your configured port 8080 it will not start

[stable sphinx]

tcp 0 0 127.0.0.1:8080 0.0.0.0:* LISTEN 44869/ustreamer right, Ive actually found ustreamer running on port 8080

[cobalt heath]

It is listening on localhost port 8080, now you have to ensure nothing else is running on port 8080, so that nginx can react as reverse proxy

[stable sphinx]

Thanks, ill try to move the service running on port 8080 to something else

I have all those running behind a reverse proxy so it does not actually matter on which port they are

[cobalt heath]

If you have already a reverse proxy configure it to proxy localhost:8080 for ustreamer and remove /webcam/ from url

Like 192.168.x.x:8080/?action=stream in mainsail

Also:
Whats the best way to unplug my printer from Klipper? I have the "server" running 24/7 and I only start my printer when I actually want to print something so ill just pull out the USB cable and Ignore the errors Mainsail is giving me.

[stable sphinx]

I meant I have a reverse proxy for the other services running on that machine which point to a subdomain but I dont want to publish the Mainsail Instance and all of that

[cobalt heath]

There is now best way in any case you cut connection between service and printer (due powerloss or usb disconnection) it will produce massive logs with errors and requires restart of the according service

[stable sphinx]

So just unplugging it and then restarting the services when I need the printer is the best way?

[cobalt heath]

But tbh, mixing an IoT service like klipper with eventually security related services like selfhosted Pages VPN or smthng similar isnt a good choice. I would strictly seperat them.

[stable sphinx]

Thats what im doing

[cobalt heath]

As said, there is no best way. You could do that but with mentioned downsides

[stable sphinx]

Okay, thanks

[cobalt heath]

Then I might misunderstood you...

[stable sphinx]

So basically:

Nginx Proxy manager requests wildcard SSL certs from cloudflare and if I for example go to: cloud.example.com I can access my Nextcloud instance but I dont want the klipper services open to the internet to I did not add them to Nginx Proxy Manager

[cobalt heath]

But both are running on the same host hardware right? Thats what I meant I would physically seperate them.

[stable sphinx]

Yeah, all services ( except klipper & mainsail ) are running in docker containers on the same host

Ayy Its working!

Thanks!
